My friend is in this video!
I wonder if the military still does it like that. There are more than 3 or 4 religious categories of people. :(
I understand this story as a metaphor, but I find it a little hard to believe that this is how the military would ever have done this. For one thing, not everyone attends religious services the same day--not even the all groups named in this video. Jewish folks have their sabbath on Saturdays, not Sundays, and I suspect the military allows people to attend services on the days traditionally associated with their religion. (Also, not all Protestants observe Sunday as the sabbath.)
This video is a visualization of a true story that you can find here:http://www.lds.org/general-conference/2011/10/dare-to-stand-alone?lang=engI went back and looked at it, and it says it was at the end of WWII. Different times, I guess. :)
