Is it possible for navy seals to transition to the marines force recon?

Probably, but you wouldn't want to, often guys go from Force Recon to SEALs. SEALs are the top, if someone wanted to stop operating, they would transition to a job still involved with the Navy Special Warfare community, not to another branch or to a different community, you don't go through the things you have to in order to be a SEAL just to go back, SEALs start off in things like Force Recon amd Army SF. Being a SEAL is the ultimate goal
