They could have been Hispanic or any immigrant outside the U.S. Most of the Hispanic babies coming through the system are not circumcised. It’s not common practice in their country of origin.
Guys I knew were anglo. What may be the kicker is section of the country they came from. A lot of country and southern boys served, maybe not as customary there.
Not to be gross, but one of the guys was more off than the typical Marine: he had them save the scraps in a bottle filled with alcohol.
