Example: you have 20 years of working. You spend 4 years in the Marine Corps and become a Sgt. You want to get out of the Marines and join a police force, and spend the 16 remaining years working as a cop and adding to your rank. Basically, moving from the Marines to being a cop, but not losing rank and having to start at the bottom.
I think I should reword this differently. I’m actually asking for my husband, who has two years left in the Marines. He has always wanted a military career, do his 20 years and retire and then work as a police officer. His buddy told him he could get out of the Marines after his four years and enter a police trainning program to become a police officer, and the four years spent in the Marines would count towards retiring from being a police officer. His thing is, he already spent 4 years in the Marines, so he has 16 more until retiring from them. But if those 4 years can also count if he were to become a police officer, he would rather do 16 more years as that…so Im asking if what his buddy told him was correct, or would he be getting out of the Marines and starting at 0 years and have 20 to go.
