While I have a great deal of respect for anyone that has served, I'm not sure that it pays to call out other branches. Yeah, it is fine to be proud of one's branch of service. Before diminishing the Army, perhaps a perusal of the document at the link below can shed light on which branch seems to have had the most casualties.
American War and Military Operations Casualties
U.S. Army 1966 to 1969. NOT a Vietnam vet.
Ease up, it was a joke. Anyone who served in any branch of the military has done more for this nation than some activist beating on a drum in a kids face. I suspect he might have found himself on his a-- if he tried that with a real veteran.
