I would recommend this game if you are wanting to play with a community, or a group of friends. You can play anything in this game as long as it's out there. This is also pretty utilized pretty heavily with the Zeus Game-mode. You want to play as a Modern 1st world country or 2nd world or 3rd world country and do military ♥♥♥♥? You can do that. You wanna play as a Star Wars military Trooper? You can do that. You wanna play as a Halo Marine? You can do that. Wanna play as a World War 1 or World War 2 Soldier and get PTSD? You can do that. You wanna play as the Vietnamese Soldier or a US Soldier in Vietnam? You can do that. ArmA is one hell of a archaic game, but hella addicting, and it's fan-base is actually really chill to full-time dumb-asses based on which unit you run with, but it's all your finger-tips as to what you want to do.

Currently, I run with a Astartes Unit for 40k ArmA that does combined arms Warfare, If you wish to join, here is the link: https://discord.gg/SZyREuV6HB
