Another good place to go to get a good feel for what it's like is
http://www.military.com.
Go to the top menu to "entertainment", and choose "shock and awe". When that pops up, click on "video gallery".
There are a great many videos from in-country there. Some of them are captured footage shot by insurgents. Two that made an impression on me were one in which
an insurgent is operating a small mortar by himself with a buddy videotaping him from nearby. He probably had a dud round in which the rocket motor didn't ignite, didn't notice, and dropped another round on top of it in the tube. That was the end of his career as an infidel-killer, and probably the end of his buddy's career as a combat cameraman. It's also a graphic lesson on the importance of listening to your trainer when he/she tells you how to clear stoppages.
Another example of poorly maintained equipment in the hands of insurgents. This is a video taken during a training session with a recoilless rifle.
The weapon is obviously in need of maintenance, because it ruined their whole day.
Here's some footage of the Iraqi Army with civilian volunteers taking on some insurgents down the street from them. Their tactics are very similar to that of the people they are fighting...
Spray and pray.
Another was a group of insurgents who decided they'd videotape their assault on a US roadside checkpoint for posterity and bragging rights. You get to see their planning session, their psych-up session, and the assault itself. Since their "plan" was basically driving up alongside the checkpoint and firing from the back of a pickup truck and from inside a car following it, you get an excellent example of my earlier statement about the level of strategy and tactics they learn in their training camps. The last thing their camera sees is the viewpoint of the cameraman as he tries to run away when they get themselves chopped into hamburger. And then the camera falls on the ground when he doesn't make it very far. An enterprising US soldier then decides to finish their documentary for them (very kind of him, wasn't it?) by getting footage of what's left of them with their own camera. No link - I couldn't find it with a quick search. It might have been taken down as too graphic because of the ending.
