Way too many to count but in just the recent generations
Daddy was in the Navy in WWII, both Granddaddy's in WWII, Daddy's brother in WWII, two of Mama's uncles in WWII
Brother in the Army during Viet Nam era (he was stationed in Hawaii though)
Honey was in the Marines
Son was a Navy corpsman
Nephew was in the Marines special forces, did two tours one in Afghanistan.
Best friend career Army special forces, he could tell you what he did but he would have to kill you with a pen.
I have had a grandfather and uncles from every single generation on both Mama and Daddy's side of the family who were in the service as far back as I can trace, which so far has been the 1400s. Even had 2 times great grandfather's who fought on opposite sides of the war of Northern Aggression (I'm southern and that is a joke so no flames please).
