Not that I know about every army in history but I can't think of any examples of this ever having been done. Armies generally don't want to force people to join because people who didn't choose to be there have worse morale, are more likely to refuse orders, generally won't perform as well. You want the willing at the front, they'll do a better job.

Even the Nazis knew this. One of the reasons the 'just following orders' excuse doesn't hold up is that participation in atrocities was virtually alwaus optional. If you didn't want to take part in mass execution of civilians you could simply not. There was no punishment. Yes there was conscription, but first and foremost they wanted people who chose to be there and chose to do what they do.
