To Marines, it is TBS ( The Basic School)

CONGRATULATIONS to your daughter.

Dear Ramonan, TBS (The Basic School)is the followup officers school that follows OCS. Best to you.

Incorrect. TBS follows OCS. Two separate and distinct schools at Quantico.

To be in character, you must now humbly apologize for your glaring mistake.

I thought TBS was the follow-up to OCS. Even after commissioning from the Naval Academy, the new Marines do go to TBS. Can any Marine officers or DIs clarify?
