Just pointing out the obvious. People like Honore are on the ground getting things accomplished, while armchair generals like yourself do little more than post whiney screeds second-guessing their decisions.
Too bad, but I'm sure Honore will get the job done even as you moan and complain about his language.
On the video, I didn't see him make troops "sling" weapons. I saw him getting people to point weapons down.
There is a reason for this. The reason is so that if a gun goes off unintentionally, the bullet goes into the ground instead of into the guy next to you. If the gun is pointed up, the bullet may not hit the guy next to you, but it might hit somebody's kid on the second floor of the house you're standing next to (they were in an urban area).
This is the reason why troops are supposed to point their guns DOWN. On Iraq footage, you see troops on patrol, they are pointing their guns down except when actually firing at an enemy
