The 9th Ranger Regiment is a Semi realism WW2 Ranger unit focused on delivering a grounded experience of WW2 combat. If you couldn’t get into World War 2 because of insanely casual units and it pissed you off because you’re autistic like us, then the 9th could be a good home for you. The 9th is a platoon oriented unit that focuses on small unit tactics and the enjoyment of the player. We have historical accuracy within the unit yes, but have a deep understanding of what keeps players wanting more. Outside of the game there is no yes sir no sir bullshit that comes with other units, but when Op time comes around we flip the switch to a serious infantry combat experience.
