recruitment

Hello Rabbi Michi.
I’m a Haredi guy, classical and studying in a pretty good yeshiva.
I am indeed quite convinced that there is no plausible justification for us not enlisting (within the framework of the new brigade, mainly).
My question is, do you think it is right for me to actually enlist? That is, if I were a completely independent person, I would certainly do so. But in the real situation, such a step would come at a very heavy price, socially, family-wise, etc. as you know. Now, even at that price, if I knew that my personal enlistment was of great significance, I would probably be willing to pay the price. But after all, this single enlistment will not change the equation of anything and nothing, for something to change for the benefit of reserve soldiers, for example, a much larger general enlistment is needed. Therefore, I wonder if I am morally required to ruin my life for something that does not contribute very significantly?
With thanks
