They aren’t for dropping directly into an airfield, that what we have the 3x Ranger battalions for. Funny side note, when we talked about making a 4th one of those, the planned specialty wasn’t airfield take downs, it was subterranean warfare as a unit model.
Again, hearing a Navy and Marine officer tell me who has to go live and breath at the warfighter what the Army will/wont/has/hasn’t done is kind of humorous. I don’t think there is any way the risk calculus of a single brigade air assault (which is really a badly named rapid reposition and staging) in a 24 hour period makes sense to execute as COA 1. That doesn’t mean for a second the Corps commander doesn’t want that option on the board to force the opponent force to look at the map and hold whatever reserve needed back IOT plan for that contingency. You’re the opponent commander dealing with an invasion from the North and the South now. You drop 1000 troops into Bashur… ok opponent commander, is this the opening of something way bigger you now have to handle? Is this some location you can afford to lose?
Again to Hotdogs point, “we won’t do that,” is no different or dangerous a phrase than “that’s the way we’ve always done it.” Airborne costs us very little for the capability it requires to the threat it poses. Compared to the Strike Divisions I can have a Division for less than the cost of a single ABCT, and I can move it way faster, in a host of ways that will never primarily be the jump but will always be capable of it. You now as my opponent have to respect that capability no different than you have to respect my Armor which would never do thunder runs up a highway, to the limit of its combat power in the form of track life, only to then conduct massed Armor/Mech convoys sans dismounted infantry support in an attack to seize key terrain and territory. That force would never do that… just as we would never use an Armor division to conduct a feint, while lower lethality forces formed the main effort drive… except we did both those things in 91 and 03. 1st Cav Division is the reason the Marines were able to conduct actions into Kuwait without response by a superior mechanized formation, not VII Corps doing the left hook. We put the single most powerful Armor formation on what was the historic invasion route and forced Republican guard units to respect that threat and hold in place while the Marines pushed up into Kuwait.
Why have a relatively low density capability in having airborne units? The same could be said for the Marine Corps. It’s one more problem I’m gonna bring to the fight that you now have to account for and apportion limited capability to deal with.
