Whether this is your first post or the latest post you have read at Mil Sim Junkie I will continue to re-iterate this: assess and progress.
What do you mean? Assess the problem or situation at hand and progress to completing the objective.
In short think quick on your feet and think smart. Ive done my share of stupid things in airsoft; for instance taking point on a corner when I clearly saw a teammate get shot (FYI thats a no-no).
