I bet he's glad he held a commission in the Navy.
If he hadn't been commissioned, he could have spent some time as Seaman Semen Sementchenko.
Semen like Sement. Never heard of it. Something European?
Seaman would have added a bit of interest! :D But, I understand “Semen Sementchenko” is his “Noms de guerre” or ‘war name’ adopted for security reasons, i.e. members of the French resistance during World War II, military special forces soldiers, etc. I do not beleive he has revealed his true identity.
