By deactivating the reserve battalion last the Corps save itself a LOT of money on maintenance and consumables because they're only in use once a month (for the most part) but maintains the ability to field armor if needed.

There are significant problems with maintaining such a force structure in the long run tho. Around half of USMC reservists are prior active duty and when the active tanks go away so does that pool of already trained/experiences manpower. Then there's the issue of the elimination of bridging units, and the fact that reserve units rarely get to actually train in amphibious operations.

So for all intents and purposes once the last active duty tank battalion is deactivated so is USMC armor. So the question is ... When is the last active duty tank unit due to be deactivated?
