And not every other unit is going to have that same level of logistical support, either, which would make it that much worse.
@Maj. Bill Martin That is VERY true,and it MUST be pointed out that back then SF didn't have our own aviation outfits. These were pilots and crews from units like the 4th Infantry Division giving up airlift support and cover,and besides the helicopter gun ships,it was USAF and USN pilots in fighter-bombers giving us close air support. It's a crying damn shame these people never got the credit they deserved. WE were all volunteers going into Laos,Cambodia,and North Vietnam of our own free will,and we could even quit anytime we wanted by just saying "I quit".
THEY didn't have the luxury of being able to volunteer,never mind the luxury of saying "Nope,not going to do it again." Yet they still jumped into their helicopters and flew to our rescue,knowing they were going to get shot at a LOT trying to extract us,and that if they got shot down,the only hope they had of rescue was the very 6 man recon team they had been trying to extract. On one of their normal missions,they would have had virtually unlimited access to aircraft and crews to try to rescue them if they were shot down.
I hope that one day these men get the recognition they deserve.
