What @Ari Knobler said is true.
This is just plain slander and laughably untrue. For this to be true, thousands would have to be going OTD every year and that just is not true by any stretch of the imagination. The RZ Tzibbur would literally be unable to run a Shul or minyan if this were true, much less the 80 thriving Yeshivot Hesder and the numerous Pre-Army Mechinot.
It is as I have said: Those who go OTD in the Army by and large are those who were looking for an excuse to do so.
