Considering that only 15-20% of all American LTC's go on to command battalions, it's apparent that CGSC is designed to produce staff officers. Guess that's just how it goes when the personnel system is still designed to accept a large influx of draftees into the active forces as per the Industrial Age model.

Fully agree with GBNT73's comments. Individual level learning - and desire to learn - is evident...but it's a case by case basis.
