in our class (second to last) we had 48 start and 28 commission. 18 were original to the class. This kind of attrition was normal for most of the classes while I was there. The RI move was consolidation of all officer training schools (DCO/CWO school, OIS, OCS, chaplain school etc), so once again- it was $$. For those who rolled out of the last class due to illness (rabdo, heat cases) many were given the opportunity to go up to RI. For those who had ongoing medical problems and were not likely to class up soon, they were given the boot (ie: one guy with a shoulder problem). For the sh!t bags who were languishing away in H not doing anything to prove they wanted to class up, they were given the boot. Almost everyone who wanted to continue with training got the opportunity.
