Ok, I am having problems imagining this... so if the snipers can't see the top of their pipes once shaved down... is it because their helmets and faces are camouflaged that the snipers can't see their faces? I mean, removing half to an inch off their pipes doesn't seem to conceal the smoke coming off of them, nor their faces if they held the pipe normally in their clench... or were they positioning their pipes upwards, like submarine scopes?During WWI men in the trenches would often shave down their pipes to create a lower profile to help conceal themselves from German snipers.
