Strick camo rules if you don't have the camo buy it or don't show up.
Make sure the rules of ingagement are followed to the T and adhered to.
Have roe's issued to comand atleast 3 weeks before game so that comand knows whats going on and are able to set up comunication with there squads.
Having props is a big bonus.
I have played both Blacksheep milsim and Lion Claw orginized games both are different on how they run it but both are hardcore milsim events.
