Combat Medicine

Before we go on, a strong word of caution: Very Graphic! Do Not View if you're not a medical person or if you're squeamish. The first clip, in particular -- a live firefight with casualties [skip 5:30 to 6:00].

My question: Do you think these are isolated incidents (nobody's using gloves), or is this common practice in the military? Because if it is, it's very surprising, not to mention disturbing.
