Religious Representation in the Armed Forces

No, this isn't a 'women/gays in the military' debate with a twist. This isn't about muslim soldiers in the army, or buddhist, or jewish, or whatever. It goes without saying that in first world liberal democracies, religion doesn't matter in signing up for the army. The issue in question here is the presence of chaplains.

The British Armed Forces recently appointed Buddhist, Hindu, Muslim, and Sikh Chaplains as part of the miltary.

The status quo for most first world military is (at least as far as I know) is to have a Christian/Catholic Chaplain.

Possible questions would be, should we even have chaplains in the military in the first place?
If so, should we have different chaplains according to the demographics of soldiers in the military?

Second question is kind of one-sided. You can worm yourself out of it, but it's going to be sneaky, and unfair.
