Steve, give us your insight on this one. There are two theories as to the American tactical performance in VN and the use of choppers. The first says that American troops, when landed in hostile areas, became fixated on being near the landing zones, so that they never went out aggressively to seek out and destroy the enemy. The second theory says that, like the bocage countryside in Normandy, the terrain in VN made maneuver by foot difficult, if not impossible. So, instead of destroying the enemy by maneuver, the troops in VN, like those in Normandy, had to remain relatively fixed and destroy the enemy by firepower. Which is correct? Anyone?
