I was in the Marines from 75-83. Pregnant WAM's were discharged. I went to school for a new Inertial Navigation System with 2 other people. one female Marine. We were set up in a 3 bedroom apartment for 6 months, with a generous per diem. Must have cost the military a fortune. The female gets pregnant shortly thereafter, gets discharged. She comes back after the baby is born as a rep for the military contractor.
