Apaches are completely armored, tub under, plexiglass windscreen. I have challenge that the apache was shot down with a rifle. I have seen these things take abuse in the field, and there is absoluetly no way it was taken down by a farmer with a rifle. IIRC, the Apache in question crashed due to flight computer problems. The US army tests their equipment before being sent into battle, and one thing tested is armor.
Besides, knowing the quality of a farmers firearms (non-maintained, usually pieced together from several different rifles), and the notorious inaccuracy of the average Iraqi, to suggest to the rest of the world that a multimillion dollar machine was taken down by an illiterate indigenous person is a classic David and Goliath story. However, this ohe was entirely untrue.

Also, this was reported in Afghansistan during the 80's as well, that Mujahideen were shooting down Hind choppers. This did happen, at least once, until the pilots had their glass replaced, And learned to fly higher than the ridgeline (the cockpit configuration is one pilot ontop of the other).
