I tried googling it numerous times and could find nothing about it. Thank you Ken for the historical perspective.

I know it never comes out even but looking at the possibility if squad sizes increased would we increase vehicle capacity or increase the number of vehicles? Personally I'm a fan of the insert an infantry company plus with three CH-47's and extract with 2, 70 personnel per bird + 15,000 foot mountain passes makes for a lot of puking soldiers and over torqued aircraft.
