I knew of a few crappy corpsman. There are as many bad corpsman as there are bad marines.
I've got to admit, I've got a soft spot in my heart for corpsmen....
My uncle was a conscientious objector during the early 60's and became a Navy Corpsman.... he saw more combat than all my other uncles except my pop.
a corpsman saved my dad's life during an ambush in Chu Li..........some of the guys in my dad's platoon told me my dad was sticking his leg back on and giving cover fire for his LT and radio operator who set off a booby trap...corpsman knocked him down, started an IV ... He got sent to the Naval Air Station in Corpus Christi and I got to see a bunch of guys whose lives were saved by corpsmen, chopper pilots with brass balls, quick work by field surgeons and a really sharp vascular surgeons in the Philippines.
I heard stories for 26 months at the NAS about corpsmen.... so I know that corpsmen can be turds and some Marines can be turds... but I like to tell my son that there are still heroes around...
