I know the cut off age for the United States Marine Corps is 25. I am 21 and was wondering, if I join the Navy as an FMF Corpsman, and serve my 5 years...would I be able to change branches to the Marines at age 26 or is the age cut off at 25 mainly for civilians?
The age is for civilians, you can get the age waived for prior military service. Talk to the recruiter - he can give you all the details.
age cut off is 28 marines
