Before you apply
What you need
Four hard requirements and two things to sort out before your first Sunday. That is the entire list.
16 or over
RequiredA hard requirement, no exceptions. Operations run to 2200 UK on a Sunday.
Arma 3 with Apex
RequiredThe base game and the Apex expansion. No other paid DLC is needed.
A working microphone
RequiredYou will be talking on a section net from your first night. Accents and cheap microphones are fine; silence is not.
Discord
RequiredWhere orders, slotting and the rest of the unit live. You link it to your account here for RSVPs and roles.
The modset
Before night oneOne Steam Workshop collection, free, subscribed once. Download it before your first Sunday — it is large.
Most Sundays free
Before night one1900 to about 2200 UK. Missing one is fine if you say so; missing most of them is not.
What happens next
Application to first operation
Application
You submit the form at the bottom of this page. It goes into the same staff queue as everything else on this site — there is no separate inbox and nothing gets lost.
Review and a chat
A recruiter reads it, usually within a few days, and invites you to an informal conversation on Discord. Fifteen minutes, mostly you asking us things. Nobody is testing your Arma knowledge.
Combat Infantryman's Course
Your first training night at ITC Catterick. Weapon handling, section formations, contact drills, casualty care and the radio. Run in-house by our own instructors, and it starts from nothing.
Posting
You are posted to a section by assignment record, given a callsign, and slotted onto the next operation. From that point your file starts filling up: courses, awards, operations attended.
The application
Tell us about yourself
Read by a member of staff, not a filter. Short answers are fine — we are interested in whether you can make the night and what you want to do, not in an essay.
You need an account before you can apply — it is the same account you will use for your service record, RSVPs and forms.
Before you ask
Full FAQ →Do I need milsim experience?
No. Most people who join have never run in a structured unit before. The Combat Infantryman's Course starts at weapon handling and section formations and assumes nothing. What we do need is that you take direction on a radio and turn up when you said you would.
How old do I have to be?
Sixteen or over, without exception. Operations run to 2200 UK time on a Sunday and the voice comms are adult, so we do not make exceptions for younger applicants no matter how good they are.
What do I need to own?
Arma 3 with the Apex expansion, a working microphone, and the Discord client. The modset is a single Steam Workshop collection you subscribe to once; everything in it is free. You do not need Global Mobilization, Contact or any other paid DLC.
I am not in the UK. Can I still join?
Yes, provided 1900 UK time on a Sunday works for you regularly. That is 2000 in most of western Europe and early afternoon on the east coast of North America. We have members across Europe and a few in North America; what we cannot make work is a timezone where the operation lands at four in the morning.
How long does an application take?
A member of staff reads every application, normally within a few days. If it looks like a fit you will be invited to a short, informal chat on Discord — not an interrogation, mostly so you can ask us things. You are told either way.
What is the actual time commitment?
One operation a week, Sunday 1900 to roughly 2200 UK time. Training nights and the Thursday orders group are optional for most members and mandatory only if you hold an appointment that needs them. That is it — there is no attendance quota beyond turning up often enough to stay useful to your section.
What happens if I miss a Sunday?
Nothing, if you say so beforehand. Mark yourself as not attending on the event, or submit an LOA if you will be away for a stretch. An LOA record exempts you from attendance statistics for its duration, so a genuine absence never counts against you at promotion time.
How realistic is it, really?
Realistic where realism makes the fight legible, and compressed where it does not. We rehearse section drills, use correct radio procedure and give orders in a recognisable format. We do not do drill practice, saluting outside of operations, or eight-hour patrols to nowhere.
What is the modset?
A single Steam Workshop collection covering British kit and vehicles, ACE for medical and interaction, ACRE for radio, and the terrains we run on. Subscribing takes one click; the first download is large, so do it before your first Sunday rather than on the night.
Do I have to use voice?
Yes. Arma milsim does not work without it — you need to hear your section commander and they need to hear you. Accents, nerves and a cheap microphone are all fine. Silence is not.
How do promotions work?
On time in grade, the courses you have passed, and whether you are already doing the job. Every promotion is a dated record raised by a member of command and visible on your public profile — including the ones that were later voided and why. Nobody is promoted by asking.
