Out of curiousity, is there any need to have religion on the ID discs any longer? Or is it just an anachronism.
Seeing as, should you fall on some foreign field, I'm pretty sure that no matter what, your mortal remains will be returned home. I stand-by to be corrected, but I thought the reason religion was on the dog tag was so that back in days of yore (WWI, WWII, Korea, etc), protestants weren't being laid to rest by catholic clergy or vice versa, although I admit I am not elightened as to the cosmic consequences of such a travesty.
