You guys don't have a clue.
I have a few clues. Been in similar situations overseas, and I train soldiers stateside. It is fine and dandy to admire the courage of the soldiers in the video, and I certainly hold no sort of ill feelings towards them, but for those of us who have been in those situations and will be going there again, critiquing poor combat performances is necessary.
The SAW gunner was by far one of the best of the bunch. My only critique was he should have slowed down his rate of fire well before he realized he was down to a 100 rds.
Many have mentioned that he was doing the right thing by suppressing so his squad could maneuver. He did a great job of suppressing, his squad did a terrible job of maneuvering. Judging from the sound of the incoming there were about 2-3 enemy combatants, who successfully pinned down at least a squad for about 20 minutes, before finally forcing them to withdraw. That is embarrassing to anyone who wears the uniform or has any pride in our nations fighting forces.
The worst part was the riflemen, equipped with ACOGs no less, who did not take advantage of the SAW gunners suppression to acquire, identify, and engage the targets. I often mock the "hadji" firing position when giving basic rifle marksmanship classes. The two riflemen in this video provide perfect examples of this position, firing blindly over their heads while not even attempting to aim the weapon.
