Y'know, all of you that see a problem with the Academy providing a place for Moslems to pray, you're right. Eliminate all of the 'places of worship' in the Academies and millitary units worldwide. My tax dollars shouldn't go towards any religious services for Christian, Jewish, Hindu, Bhuddist, or Muslims. We're paying these soldiers to fight, not to go to Church/temple/mosque/etc. If any of them want to pray, do it on their time, and their dime.
George Washington started the Chaplaincy in the Continental Army. He considered Godliness an essential virtue in an American army.
Tellingly, "godliness" in Muslim armies means a much, much different thing than "Godliness" in a Christian one. Usually the opposite, in fact.
But, as Washington was the founder of this institution, I can see why some (ex)Brits such as yourself might be against it. You didn't have him (or us) figured out the first time, either.
