I don't know how widespread the practice is, but my personal experience in the US Army was that some commands at the platoon or company level encouraged participation in church services, and those that didn't go would be assigned to do work on Sunday.
It's a shitty practice, but I went along with it, because an hour napping in church beat the fuck out of cleaning latrines.
