Through OCS, TBS, and MOS School, there is no difference between the two - all Marine Officers receive the necessary training to lead Marines in combat. The differences in careers occur after MOS school.

 

Active Duty 

Marines will check into their Fleet Unit after MOS School to begin leading platoons and staff sections. Planning exercises, writing LOI's, setting policy, dealing with troop discipline, etc will all be regular occurrences to the Active Duty Marine. They will work for the Marine Corps full-time.

 

Reservists 

After MOS School, they check into a reserve unit, then resume civilian life. They find a place to live, a job, etc. These Marines lead normal lives as students or working professionals - teachers, firefighters, bankers, engineers, etc. Even when they aren't drilling, they will be planning exercises and training for drill weekends and annual training blocks. It's a large commitment.

​

Reservists will typically "drill" with their reserve unit one weekend a month and a two week block once a year. During drill, Marines perform annual training and other tasks to maintain their technical proficiency in their MOS. The two week block is meant to test and train the unit to keep skills and readiness levels high. Officers are responsible for planning and leading these events.

​

In the event of war, disaster, or other emergency, Reserve forces may be activated for longer periods of time. 

 

The decision to be Active or Reserve should not be taken lightly.  By speaking with your recruiter, your family, and by weighing your near and long term goals, you can make the best decision for your situation.
