to prolong ETS for trained soldiers, an example is 2nd Brigade 10th Mountain is on its 5th deployment, its not because the Army hates the 10th its because the of the retention and quaility of the troops which don't mind long consecutive deployments. As you know its best to keeps your trained A team in as long possable, I also recall the real "stop loss" was mostly aimed at the reserves.

Voluntary retention of active troops is still at historical highs, if something does not change I am sure that will not be the case.
