Hey, at least it's better than some armies where recruits are
discouraged to drink water.
In the Korean Army where I served my NS, recruits are
discouraged to drink water by their NCOs and stupid sh!t like that.
I suppose the purpose is to "toughen up" the pukes and instill fear
in them. Hah! Maybe such training is appropriate for elite units
who are preparing to serve in a desert environment or something
like that, but I always thought it was foolish and dangerous for
recruit training, and only served the egos of the
NCOs.
The only result that I could see were people fainting and
collapsing. Fortunately, I had enough sense to disobey orders and
secretly sip some water when I thought they weren't looking. (I'm
SO evil...bwahahaha. I guess I'm just not "soldier material").
But I got to agree that drinking 3 litres of water is pretty
stupid, too. But then again, an Army (of any nationality) is not
known to be led (or followed) by the brightest minds.
