Full Spectrum Warrior.

Well this new game i have been playing has aparently been used by the US Army for training purposes.
I am worried.
Mainly because of the incident which left 2 of my team members dead.
Observe.

The basic set up was one man hiding at the end of a alley leaning out and shooting at my men.
So i put my 2 teams as so.
Set up 1
With "A" & "C" on one knee with "B" & "D" shooting over their heads.
I left this go for about 5-10% of my ammo.
Then i pissed team 2 off and set team one down the alley to maybe, i dunno...... kill this guy!
Set up 2
I left them like this for a while maybe for another 5% of my ammo. "A" & "B" were injured, but could keep figting.
ENEMY STILL NOT DEAD!!!!
Set up 3
Lets try this out then......
Outcome
Nope that didnt work...
"A" & "B" died, mission failed.
WTF
why cant they kill 1 man.
they have 4 times the guns!!!!
wtf!!!!!
stupid game!
