The definition on MILSIM has never been, and will never be accurately defined.
Personnally, MILSIM has always been how much effort, dedication and devotion a player / team puts into the game to fully live the immersion.
And then of course, you have the fluffy-candied things that comes with it; Props, Chain Of Command, Vehicles, Strict gear rules, Mission Complexity, ect.
This MILSIM debate was there when I first joined airsoft in 2003, and it's still being debated 10 years later ... I've turned that page and carried on with my beliefs.
