xoB,
It was always BYO-O2 for me.
We had transportable tanks and regulator systems with multiple service outlets (O2 console) that we would anchor inside an aircraft for those of us in
coach.
It's been interesting to see how this "Immigration" thread has crossed over into aspects of the war on terrorism. It seems that the battle abroad and the battle on the home front are inextricably intertwined by politics.
BTW, many people do not realize that there are US Special Forces (a.k.a.
Green Beret)
National Guard units. They are specialists in unconventional warfare [including counterinsurgency operations and strategic reconnaissance] and they have already served in Afghanistan. Will they be deployed along the US border? I've previously
posted the opinion "...I'm confident we will win the undeclared war on illegals." in another thread. I based my assessment of the situation upon this capability and the impact of the border threat upon our politicians. It was an educated guess: my military service was as an active duty SFer. Here's a handy listing of
SF units (past and present) for anyone interested.
