The Army hasn't been this broke since the outbreak of the Korean War in 1950.
In the time since I was in (81-02), the ONLY acceptable reason for a unit to be below C-2 was if significant portions of the unit were already deployed. If a unit was C-3 or C-4 for ANY other reason than that, the commander would be virtually guaranteed to be relieved of duty. MAYBE he'd get one month to fix the situation, no more.
And in the days of unannounced ORI's, God help the commander who faked a SORTS report.
