The cobra gunship was spectacular to watch. When we were being mortared, the cobra pilots would go up and try to take out the offending VC and his mortar tube. In the dark of night, watching the white streaks from the rockets and red tracers from the mini guns was surreal - almost like being in some science fiction movie.
There was one period of time when a particular VC would roll his mortar tube out of My Tho, hit Dong Tam, then roll it back, knowing that it was against the rules for the Americans to fire on a "friendly village." But one night, my friend, John, got him before he could get back.
