It's a game
but for some people that game involves authentic kit, matched to their team mates. Regular training, and the agreement to follow a chain of command.
this does not mean that they are "serious" it just means that they play the game differently.
for some people, digging in , sitting in a trench all night in swarming bugs and not seeing let alone shooting anything is a great night of "airsoft"
For others, not so much
