For all those who oppose the change, like this guy, please provide specific predictions of all the bad things that will happen, along with a timeline, so we can come back later and see if you were right. "A plague of locusts o'er the land" is too general -- please predict something like "10% reduction in legume production in the southeastern U.S. due to Orthoptera infestation in 2011". Likewise, rather than "re-enlistment rates will drop like a rock" say "re-enlistment rates will be down 45% by the end of 2012" or something to that effect. (Anecdotal, non-statistical predictions like "I'm going to be molested by a phantom pole-smoker in April" are also accepted, but please be prepared to provide verification if your prediction comes true.) Anyone on active duty who plans to leave the military because of this are especially invited to comment -- let us know your EAOS, and please check back in when you follow through.
On the other hand, if you think the military will adapt to this change as it has all others, you can say that too.
