The 1-74th Infantry Regiment is a new Arma 3 server, based on an American Armored Infantry Platoon.

It is a friendly community, run by long-term friends with members from both Europe, and America.

Operations run every Saturday @20:00 CET/14:00 CET except on Holidays.

The unit rotates roles every month, so new leaders are able to take over and make minor changes without changing the overall experience. Players get to use different weapon systems that they desire. Pilots get both ground time, and flight time.

The goal of this server is to run at the smaller platoon level. Most Servers are over ambitious, and try to run entire companies, battalions, or even massive scale operations. What this leads to, is very, very little infantry action on the ground, and a warthunder experience. We fight closer with the enemy, clearing buildings, fighting with grenades and small arms, as well as calling for fires, and providing armoured support by fire.

You'll get to know your squard, with 3 squads of 6 on at the same time, some times more, we're able to run an authentic experience that's fun and cinematic with less players, without losing out on the quality.

Don't subject yourself to playing with 3 infantrymen trying to compete against a hundred tanks. Fight next to a dozen other players on the ground, seeing the scale of battle in a way that is cinematic, deadly, and provides excellent screen captures.

The 1st Battalion, The Rifles is British MilSim Arma 3 unit where fun meets discipline and realism meets creativity.

We focus on delivering immersive, well-structured missions that test your skills in counter-insurgency operations across unpredictable, high-stakes environments. Every engagement is a chance to prove yourself as part of a professional, cohesive team.

we're looking for motivated players to fill key roles. Whether you’re a seasoned veteran or new to milsim, you’ll find a dedicated, welcoming, and professional environment here.
