I like it. I've proposed a similar in-theatre Recondo school for training divisional LRRP companies for long-range reconaissance patrolling.

I've also proposed a similar multinational [NTO] "raider" unit for use by Corps level HQ (1st Interallied Commando).

For your concept, I would change the name to
Raider Companies. There's precedent in the U.S. armed forces for use of this term. Marauder is synonymous with lawlessness and banditry. It sounds cool, but after about '98, it would become confusing. Maybe the units started out designated "marauder" and then changed to "raider" later on.
