Those same troops have been inflicted with *chosen Deity* knows how many "Do it and do it now!" trainings since they have been deployed. This just gets news because it is "Oh teh noes, teh gheys is comingz!!!" I'm sure 98.5% of the troops could care less. We know how to deal with gays because we already serve with them. And the only time it ever seems to be a problem is when somebody wants to play the queen card to get out of their service contract. Which isn't, from my irritable NCO point a view, a bit different than the knocked-up right before deployment card, the sick lame and lazy card, my daddy's a congressman card, or the ever popular I'm a single dad and the kid's mom is a meth head so I can't deploy. The last one often having merit if we care about kids, not so much if it's winning wars.
The mandatory training from on high is just how the very senior military does CYA these days. Chinese put malware on every thumb drive in the world and infect the navy? Have training. SN Jones found zip-tied in the shower wearing pink bunny slippers and little else? Have training. Flush a koran? Have training. Ship stuck on sandbar unexpectedly? Have training. Actually do your job? We got training for that Hey smart-ass, figure that out on your own time, we got training to do!
That is the military's two default buttons for getting the press and congresscritters off their heels. Fire someone almost important, and training.
