As a new immigrant and relatively old(about 30 years old), I entered the army through "Shlav Bet." This was a program where boot camp lasts six weeks, and the participants would "graduate" at a level of "rifleman 3" (rova'i shalosh). Afterwards we were supposed to serve 2 1/2 months of active duty.
The group that I did boot camp with was almost entirely new immigrants, except for a couple of Hareidim. This was long before the "Nachal HaHareidi". I think that we had people who came from about 20 different countries. About one third of the trainees were religious, and this relatively high percentage worked to our advantage when we had to stand up for our religious rights.
Every day somebody from our group had to work in the kitchen. At first people avoided this job. Who wants to wash the dishes and clean up after hundreds of soldiers? But as boot camp progressed and became tougher, people volunteered to do kitchen duty in order to take a breather from our "sadistic" commanders and their demands.
One night the volunteer from our group was a clean shaven immigrant from Iran. Let's call him Moshe. He was busy cleaning the kitchen when the military base staff (the "Segel") decided that they wanted to party. The Segel was comprised of young soldiers (aged 18-21) who were doing their regular army duty. They had bought food from a supermarket in a nearby city. Among the things they had purchased was raw chicken liver, certified kosher by the Rabbinate. They placed the liver on the army's metal trays that are used to cook meat. Then they cooked the liver in the army oven.
Moshe was a religious Jew and he objected. He explained to the staff that chicken liver must be roasted over an open fire and that they are "treifing" up the kitchen. But the Segel members, products of the secular ghetto who think that they are experts on Judaism from what they read in Maariv, Yediot and Ha'aretz, would have nothing of Moshe's objections. "The liver is kosher and it has the certification of the Rabbinate," they answered.
After Moshe was finished cleaning he came back to the "Ma'ahal" (the group of tents where we lived) and told the other trainees what had happened. A third of the "Pluga" was now up in arms and the commanders realized they had a problem. The trainees went to the kitchen and took the tray that was "treifed up" and threw it in the garbage. The Military Rabbinate was notified.
In theory the staff members should have been put on trial in a military court for breaking army orders(Pekudat Matkal 34.0103). In practice, I don't think that anyone was punished.
