UPT used to be approx. 30% washout rate. Recent SUPT sqdr CC said it's about 3% now. SIE's increase the drop out rate.

Some ANG units require that candidates be in the unit. Some don't. Supply will impact the units that require candidates enlist in the unit first.

In some ANG units to be a competitive candidate you need flying experience. 500+ hrs, or more, is common amongst the candidates selected. Comm/inst helps achieve success in SUPT but it's no guarantee.
