There is little doubt that this was the preferred way for our infantry units to insert
into a new operational area. Often, it was the only way. Flights of 10 or 20 UH
'choppers' would quickly transport us to new locations, and build up the strength
on the ground very quickly - maybe 70-140 at each lift. There were hot insertions,
cold insertions, and the 'who knows' category. I was in favour of the cold insertions,
although as I recall we didn't get to choose. Mostly, it was OK. Sometimes it wasn't.
