This is the Guard; we shouldn't forget that, either for the pros or the cons. But I think the modern Aviation army, at field-grade level and higher, would require AVN battalion and brigade commanders to know a great deal about the capabilities of the infantrymen they support. the generals I knew well (all two of them) were generals not because they'd been infantrymen, but because they'd mastered the joint game. I don't see why an aviation officer couldn't do that; they all go to the same CGSC and the same War College.Here's where I think it gets iffy... I haven't been a POG very long, but I do know that a lot of junior POG officers and POG senior enlisted don't have the slightest clue about infantry stuff, down to some basic weapons handling and marksmanship stuff. I don't know any general grade officers with either background so I don't know what or when they learn certain stuff, and how that might compare. At least on the level where I'm at, there are absolute masters of their profession, but their profession isn't infantry.
On the big sand table, perhaps things are different. That said, there are certain realities of infantry capabilities that you only learn being in the infantry. I would think at the very least having some time as a platoon commander in the infantry should be looked at heavily when looking for future senior infantry leaders. I was only ever a squad leader, but I know that our reality is alien to a lot of POGs.
Plus, in the army, not all infantrymen are created equal. An 11M breaking track on a Bradley hasn't got much in common with the 11C shooting 120mm mortars out of the back of another Bradley, who in turn hasn't got much in common with an 11C humping 60mm mortars in an airborne rifle company. And infantry officers get just a small taste of all those. There's no way to guarantee an officer's breadth of experience no matter what their background.
Was she airlift, attack, or what?
