Suddenly a distant wind brings in a rocking acid riff and the sounds of salvation - the sweet chopping of the hueys. The helicopters arrive above a thick line of palm trees. They have mounted speakers on them and they're blasting All Along the Watchtower at the enemy, like a symbol of inevitable victory of the Western civilization over the degenerate Eastern savagery. In several moments the machine guns rip through the jungle like thunder from above, raining full metal jacketed death at the commie savages, defending Jesus, Democracy and the American way of life. The charlies are falling down like a bunch of rats snuffed out by the heavenly exterminator, the Air Cavalry. Red mist is spritzing from their heads when they pop under machine gun fire like ripe watermelons.
