Then the charedi soldiers will have to suffer courts martial when they disobey an order.
Are you trying to propose a system which will work peacefuly, or not?
The halachah is that when you become part of a new community you abide by the rabbis of that community. How many charedi rabbis are there in the IDF?
That’s probably not relevant here, but even if it were, realistically, it’s not going to happen, so if you want a realistic proposal, the government will have to give in on this.
The idea that non-charedi rabbis are not competent to pasken shilahs is one of the most vicious slanders around.
Maybe, maybe not. Not all charedi rabbis are competent to answer shailos either,but you’re trying to force people to accept rabbis based on government appointments, and they shouldn’t and won’t.
You are also ignoring the fact that the validity of the missions sometimes undertaken is a matter of major contention between the camps, and affects shailos such as putting people into sakana and chillul Shabbos.
