Guard and Reserve units very frequently use 'full battle rattle' when conducting a zero or qual range because an IBA/IOTV + ACH is an easy 'control' to implement to reduce the overall risk 'rating' on a DRAW/formal risk assessment.
So while SNCO's might be barking the worn-out 'train as we fight' nonsense, the simple truth is that some O3's and O4's wanted the range event approved and signed off by the O6/O7 responsible, and that Colonel or General made it clear that they wouldn't sign off on any DRAW that didn't involve wearing full battle rattle.
Forecasting ammo is a fickle thing and frequently depends on the Brigade (O6/Colonel level) and higher. Frequently they will harp on about shortages and lack of funding etc all through the entire Fiscal Year, only to freak out and go into a spending spree around mid-August.
As for the profound absence of *actual* training with handguns in the Army - at least those joes are pointing the damn thing in a safe direction. It's amazing how easily even NCO and SNCO's in the Reserve/Guard that have no other exposure or practice to rifles throughout the year can profoundly and terrifyingly mis-handle a 20in M16, let alone an M9.
