ok you don’t have to believe me.
Halacha is not only things like eating chazzir. It is being forced to hear women singing and not being allowed to daven Mincha just because that is what the commander decided and yes being told to do things that are mechalal Shabbos (agreed the commander thought it wasn’t mechalal Shabbos but even when told he refused to budge). and no the army does not go out of the way to get mehadrin food. Many soldier in the nachal were stuck with nothing for Shabbos and when the charadaim from Kiryat Sefer got organized to get then food for Shabbos the commander decided they cannot take the food. (this story was in the charadi press at the time)
But then again I can’t make you believe something you don’t want to.
