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. 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?
