Who are we? The 22nd RDF is a semi-serious, milsim unit who want nothing more but to have fun while telling rich and creative stories set within various time periods in the Halo Universe. Warhound Squadron has fought in multiple operations across multiple eras of Humanity's history. From the intensity of the human Insurrection, to the grand scale and brutality of the Human-Covenant War, the 22nd responds wherever and whenever they're needed. Be it Insurrectionist, Covenant, or maybe even something worse, we're only second to ODSTs in response time. You too, could be engaging a variety of hostiles across an even greater variety of environments within the Epsilon Eridani system, and most certainly beyond.

What kind of roles do you offer? We offer a wide variety of roles to scratch any specific itch you may have, such as....And much, much more!

• Marksmen and Sniping
• Medic (Utilizing a very toned down version of KAT, to offer you a unique and engaging challenge)
• Airmen/Pilot
• Crewmen roles
• Radio Telephone Operator/JTAC (Utilizing TFAR)
• Combat Engineer/EOD
• Armored Soldier (Utilizing specialist weaponry, from static emplacements to flamethrowers!)
• Drone Operator
• Zeus (With a HIGHLY open Zeus team who will help you every step of the way, no questions asked!)
• Active Duty, slotting you into a permanent position within one of our squads!
• Reservist, for those of you who have messy schedules, or just have to be in a certain mood to play Arma, becoming a Reservist will left off various attendance expectations off your shoulders!
• Op Guest, for those who just want to pop in every now and again to hang out! Great if you're already part of another unit!

What's your schedule like? Our Main Operations are on Fridays and Saturdays at 16:30 EST (4:30PM EST). Side Operations may be ran at any time in the week (with notice!) by both experienced Zeuses and members of the community. When joining, you get to pick from three roles of how you would want to engage with these operations!

Anything else I should know? We will never ask for any prior experience with either Arma or the OPTRE mod, and we are always ready and eager to help new players out with understanding the, admittedly sometimes messy, nature of Arma 3. Know that, above all, we are a community first. We have a major focus on player feedback with active discussions happening in weekly staff meetings, and monthly community-wide meetings, for players to voice concerns, praises and overall keep everybody in touch with one another. We pride ourselves on being a LGBT+ friendly unit, with a large majority of members being a part of the queer community. Hate isn't fun, and will promptly get shown the door. Recruitment is always open to anyone with a desire to play, and maybe even tell stories in the Halo universe. If anything has interested you at all, tap the link below, and have a great day!

Welcome to the 115th Air Assault Battalion!

The 115th Air Assault Battalion is a US Army unit that specializes in air assault and airborne tactics, as well as guerrilla warfare, small unit tactics, combined arms and recon operations. We operate at the platoon level for our ops. A mature attitude, an ability to work together in tough situations, and a willingness to work through conflicts is a must. We use a promotion point system that rewards attendance and employs a rank ladder system in the interest of even, fair progression. We encourage a casual environment outside of operation and a close, friendly community all the time. We always are open to talk with other units for collaborations. We have a very clear and welcoming chain of command willing to listen and discuss any suggestions or issues you come across.

Description of Unit Environment

We are a casual and pretty non-censored unit outside of operations. We tend to pull a 180 in operation and turn to a more baseline milsim unit. We like to immerse ourselves within the experience no matter what the operation. For this reason we prefer people be in a more serious mindset within operations.

The Office of Naval Intelligence is now recruiting!

We are a Semi-Serious, North America-based OPTRE unit based the Office of Naval Intelligence (ONI) from Halo lore.

WHAT MAKES US UNIQUE:

1. Flexible, Mid-week ops: ONI has 2 regularly scheduled operations each week, Wednesday and Friday 8-10 PM EST
2. Intelligence Agency Theming and Operations: While Wanderer wears ODST armor, all ONI personnel are first and foremost intelligence agents. ONI also often calls for more subtle and unusual approaches to problem solving, such as:
3. False Flag Operations
4. Stealth insertions and assassinations
5. Undercover infiltration
6. Guerilla and Asymmetrical Warfare
7. Expanded equipment authorization: ONI’s missions are of the highest priority to the UNSC, so extra equipment not usually authorized to ODST companies is available aboard our ship’s armory.

EXPECTATIONS FROM YOU:

• Be over 16 years of age to join, 18 to join the leadership program
• Be respectful to others, inside and outside of the unit
• Have unwavering loyalty to the Office of Naval Intelligence and the UNSC above all others!

DIVISIONS:

As of 2556, the UNSC Vagabond has been deployed by ONI as a quick response strategic asset, with the following sections aboard to flexibly respond to threats. and advance ONI's interests.

• Wanderer Company, Office of Naval Intelligence field unit: The bulk of the Vagabond’s tactical response, new ONI agents will most likely find themselves beginning their careers attached to Wander Company’s seasoned, professional, and deadly warriors
• Nomad Wing Aviation: Given the Vagabond is a Halcyon-class cruiser, it cannot provide sub-orbital air superiority or support. For that, we have the highly capable Nomad Wing armed with the very best of the UNSC combat craft for both in and out of atmosphere.
• [Redacted by Section 2] SPARTAN Company: [Redacted by Section 2]

CALL FOR ZEUSES

ONI is always looking for players interested in running missions or putting together a campaign.

Unit Name: 1st Reconnaissance CO, H&S BN, 1MARDIV

Game: Arma 3

Playstyle: Semi-Serious Milsim

Operation Times: 19:00 CST Tuesdays and Saturdays, alternating between trainings/mini-ops & main operations each week.

Who We Are:
1st Recon is a realism-oriented semi-serious milsim group, playing as reconnaissance Marines of the 1st Marine Division, circa 1993-1999. We prioritize realism with a purpose, meaning you will see realistic mechanics and challenges in-game, but you won't see the "Yes, Sergeant" nonsense common in many milsim units - it's realism with gameplay value.

Rather than defaulting only to basic "go here, kill that" missions, we maintain a variety of mission types. You'll see us doing things like small-scale paradrops, combat dives, or directing AI fire support alongside the regular light infantry objectives - of which we run both combat & reconnaissance-oriented objectives. As with many other groups, we organize our missions into campaigns, where the players' actions drive the "story", and directly affect future missions.

Each week, we generally run one main event, and one training and/or mini-operation event. Rather than assigning each to a specific weekday, we alternate them between our Tuesday and Saturday event times, so one week might be a Tuesday operation and a Saturday training/mini-op, but the next would be a Tuesday training/mini-op and a Saturday operation. On off-days, you can often find us playing other gamemodes on Arma, or playing other games - we'll occasionally host proper game servers for them as well.

In addition, we also try to keep our administrative actions transparent, and our requirements as low as possible. The only out-of-game expectation we have from our players is to respond to the event posts in our Discord - simply letting us know when you won't show up is sufficient, no explanation necessary.

United Security - 2026 Recruitment Video

Realism in execution and comms - without the full hardcore lifestyle.
Persistent narrative PMC operations with trained roles, doctrine, and a mature, flexible culture.

We’ve been running ops for 6 years - and we’re built to run for many more.

What you get here

• Structured Realism - tactics, radios, and roles used properly without drill-sergeant RP
• Persistent Campaign - actions and losses carry forward; the story remembers you
• Combined Arms - infantry, fires, aviation, and mission-specific attachments coordinated together
• Moderate Enforcement - serious in-mission; reasonable and pragmatic out-of-mission
• Training Without Ego - we teach to raise baseline skill, not to exclude newcomers
• Endurance & Stability - 5 years of continuous operations, not another 3-month pop-up unit
• Weekly Operations - Tuesdays and Thursdays at 6:30 PM UTC – each one handcrafted and story-driven to continue the evolving USEC narrative.
• Attendance Requirements - Flexible; we put real life first

How we run ops - the in-mission standard (concise/practical)

We operate with a methodical baseline that shifts into controlled aggression when the situation demands. Our goal is predictable, repeatable teamwork with narrative context - not theatre for its own sake.

Comms

• Brevity and clarity: keep channels for mission-critical info only while live. Short, informative calls > long stories.
• Standard contact reports: concise direction/distance/type + immediate action
• Radios are the tool for coordination - expect discipline, not silence police. We moderate enforcement based on impact.

Tactical discipline

• Formation & movement standards: bounding overwatch, covered advances, deliberate clears.
• Don’t self-task: follow tasking from your team/element leader unless exigent.
• Use available supporting arms correctly; call for support via prescribed channels and formats.
• We favour measured, coordinated action - move fast when needed, deliberate when you can.

Role adherence

• Roles exist so teams function: medics heal, TLs brief and manage squads, specialists use their kit.
• No “jack-of-all-trades” freelancing during assigned tasks; we ask that you play your slot so the platoon works.
• Cross-training encouraged, but respect the chain of command during ops.

Structured storytelling

• Leaders frame each op with a short narrative brief: context, objectives, and what success looks like. Actions should make sense in-universe.
• Maintain in-contract behaviour while live: in-character radio cues, mission context in decisions. When players visibly break contract behaviour, we relax enforcement; realism is encouraged, not weaponized.
• Debriefs tie to campaign thread (what we did and why), but strict roleplay is limited to the mission window.

Pace & feel

• Methodical by default; tempo rises into controlled aggression on contact or timed objectives. Expect deliberate clears, then sharp, coordinated pushes when required.

Who fits here

You want tactics with flexibility, continuity that rewards investment, and a unit that takes missions seriously without becoming a lifestyle obligation.

Who doesn’t

Lone-wolves, persistent shitposters on radio, and players looking for total LARP bootcamp or pure chaos.

How to join
If you are interested in joining or have any questions, feel free to hop on our Discord, open a ticket and ask away!

About us:

We are 9 Rifles. A British based ArmA 3 milsim unit. Formed in 2023 from members of several previous units, bringing together years of milsim experience. We represent the fictional 9th Battalion, The Rifles Regiment.

How we play:

We strive for a milsim environment, without the 'yes sir, no sir' hardcore play style of some units. When joining our operations, we want a group of dedicated, like-minded individuals. Players who can have a joke and a laugh, but when the bullets start flying, crack down hard and get the job done. We strive for a community, a brotherhood.

Who are we looking for?:

Experience doesn't matter to us. We don't require you to have a certain amount of hours played in game, or have irl knowledge of complex battle tactics. All we want are people who want to be a part of the program and who want to help us grow this community. If you're brand new to the game, we offer training to teach you the basics and will guide you to grow as a newbie. If you've got 10000 hours, we will show you how we run things and trust you to show us what you're made of.

What we offer you:

We have multiple roles for you to sink your teeth into. From being the first man in the door as a point-man, laying down lead and hate with the GPMG as a machine gunner, saving the lives of your comrades as a field medic, or blowing up armour as an anti-tank operator. If you can prove yourself worthy, you may even move further up the ranks and be able to lead your own team as an IC. There are many roles you can fill and many opportunities to show us what you're capable of.

Operation times:

We run one big operation once a week at 8pm GMT Sundays. These will usually last about 3 hours, to ensure ample time for gameplay. We also sometimes offer different types of training during the week, as well as some less serious operations to keep our skills sharp, and to allow new players a chance to improve before the major operations.

The Horus Heresy rages on, rally to us and bring ruin to the Traitors!

>Who are we?

We the 278th Cohort a, Semi-Serious, New Player-Friendly Arma 3 Unit of Warhammer enthusiasts, both New and Veteran, set during the events of the Horus Heresy in the Warhammer 40,000 universe. Specifically, we play as Cohort of Solar Auxilia, unaugmented Human soldiery clade in Void Armour, considered second only to that of the Emperors Legiones Astartes. Fighting for control of the Calix Sector on the edge of Ultramar.

Over the past 2 years we've launched numerous campaigns against the Arch Traitor's forces. Each one not only consisting of various Battlefactors, which influence how the Operations of that campaign play out. But also voted on by our Cohort members! Keeping things ever changing as the Heresy drags on. Deployments for these Operations are scheduled to happen every, Friday at 6:30 PM EST.

>Force Composition

The Cohort currently consists of...

118th Solar Battalion | Frontline Infantry & Armoured Calvary (Solar Auxilia)

2nd Medicae Battalion | Medical Support (Solar Auxilia)

45th Aviation Wing | Air Support (Aeronautica Imperialis)

401st Explorator Clade | Logistics Support (Mechanicum Of Mars)

Some Cohort Units have limited slots; some will increase in availability as the Cohort grow.

>Closing Remarks

Our Cohort is the only Solar Auxilia, unit (that we know of) in the Arma 3 community. As such we're the Vanguard; paving the way on what it means to be Solar Auxilia in galaxy set aflame. Stalwart soldiers of the Emperors Exertus Imperialis, loyal troopers who'd gladly face down the horrors of the galaxy time and time again. Be it within the confines of a subterranean bunker or on the open plains of an all out assault.

Semper Deinceps!

3rd Shock Army is a relaxed OpFor unit. What is OpFor? OpFor is any non-NATO factions - the "opposing force". We mostly do Cold War, but have done modern campaigns too. If you are tired of using the same old ACOG to snipe an insurgent from 500 meters away in a desert, we are what you are looking for. We offer a challenge and change. We fight enemies who are equal if not more powerful than us.

•  Casual atmosphere with serious teamwork.
•  Cold War/Modern with authentic equipment.
•  No mandatory attendance/training demands.
•  Platoon level operations.
•  Combined arms with no fixed roles!
•  No DLC! Just mods.

Current Campaign: We are currently playing a The Fire Rises-themed campaign where the unit plays as the American People's Liberation Army, going across America fighting for glorious revolution during the fictional Second American Civil War. With the collapse of the United States, and helped by a multitude of official military Divisions (notably a majority of the Californian National Guard forces) that defected from Federal authority, the APLA seizes control over parts of California to bring about a socialist revolution, now under a broad coalition of Jacobins, Octoberists, Anarchists, and Neosocialists. Our story begins in 2021, when contingents of the now APLA-sworn National Guard strive to fortify their position and unify the state’s military assets in order to prepare for the upcoming push Eastwards. A little video trailer we've made is available to hype newcomers to the setting!

The Experience[3SA]

The 3rd Shock Army plays predominantly non-NATO Eastern factions with an emphasis on immersive and realistic story-based campaigns with Soviet-era themes. We play at platoon strength with practical military-style teamwork. Our mission is to provide a fun Saturday campaign as our foundation and to facilitate the expansion of the unit through open-ended volunteer-driven side operations and community engagement. We do not have any strict requirements for you to join us, no attendance or leave of absence mandates, nor do we mind if you play with another unit as well. 3rd Shock also prides itself on our diversity and the acceptance of all skill levels, walks of life, nationalities, and backgrounds, but we do carefully curate a respectful atmosphere between each individual member in order to have a good time. We are a mainly European unit but we have members all over the globe and are always looking for more!

LGBTQIA+ Friendly in a time where there are unspeakable struggles in life, this needs to be highlighted on a personal level first and foremost. We aim to treat our LGBTQIA+ friends as equals and try to provide a safe space as many of us are also a part of the community.

Less Rules, More Roles

We don't reserve roles. Players are free to find the place they enjoy within the platoon, from perfecting the art of intimately serving up hand grenades in an assault team, to operating tanks and flying jets. We encourage all players to grow their skills and flexibility. We believe this allows players to experience and enjoy everything Arma has to offer rather than being confined to one role and to suffer from burnout. Roles for the most part are first come, first serve. Show up, pick a slot, and have fun!

We Make Playing Easy 

Open role assignments, first come first serve.
