Why would a platoon deploy on its own instead of whole unit?

In ODS 01-03/OIF I, my MP Platoon was OPCONed to 2BCT,3ID. We were assigned to HHC 2BCT for UCMJ and administrative paperwork. But that was when Divisions had Division MP Companies and Direct Support MP Platoons.

If that Platoon, team, section has a UIC, they can be individually deployed. This is common for units above the BCT level like CSSB subordinate units, HR Company Postal and Tsrength Mgmt Platoons, etc. I commanded a Company with individually deployable 6 and 9 man teams.

As SFC Kelly Fuerhoff said, your Platoon will be placed under the control of another larger formation. The tactical relationship could be ADCON, TACON, or OPCON.

What is your Platoon? It may clarify what will happen. How do you train? Are you attached to other units? That is how you would deploy.

As a filler for a unit. Haven't seen down to PLT, but have seen CO attached out. Depending on the Unit MOS, I know of USMC ENG being attached out down to SQD and Individual s,
