I get what Bart is saying.
During a training exercise, I remember getting our butts chewed for not staying behind cover, not "properly" timing our shots, not wearing all our proper protective gear, etc, ad nauseam...
It seems like it did not matter that our team achieved our objective with-out losing a member. The "enemy" team all died. They did everything our instructor chewed us out for not doing. He was an "EXPERT".
The few times I did engage in a gunfight I remembered the basics of what I was taught (Mostly counting your shots and keep moving), but not the particulars. I am just glad the experts were not there to critique me afterwards.
The only wounds I ever recieved was a ricochet to the leg (A little to the right and I would have become Auntie Buck
), soiled under-britches and an increase heart rate.
I was taught to use suppressive fire (Spray and pray) to help the team move. I would point in the general direction of the enemy and fire, trying to keep their heads down so either myself or my team mates could move to a better position. I was also taught to make your shots count. I was not a sniper, so the "One shot one kill" did not apply to me.
One of the reasons I enjoy this forum is because most people here are very knowledgeable, but few of them consider themselves experts. The arm chair commandos seem to not stick around too long once they realize they are chatting with real people with real experience.
People confuse experience with knowledge. Every situation is different and what worked for me may end up getting you hurt.
