About the Haredi Brigade

Hello Rabbi Michael,
I recently learned about a new Haredi brigade that they want to open in the IDF (the Hasmonean Brigade), the goal of which is to allow Haredim to manage their lifestyle alongside military service (the so-called, entering Haredi and exiting Haredi), and a document that was recently published also includes the strict halachically compliant rules that align with the lifestyle of the Haredi public.
But I think that the very idea of ​​establishing such a division misses the essence of Harediism. I have always thought that beyond all the strictures that the Haredi community practices, the separation between men and women or even kashrut, did not stem directly from a pure study of the laws of lifestyle and religious beliefs, but also to actually separate themselves from the secular community (or the Israeli community in general). This is also expressed, in my opinion, in the push for Torah study in yeshivas, which is intended not only to study Torah purely but to keep the Haredi within their protected space (Noah’s Ark, as they call it) and I think that the “Yeshivas Nosherim” is quite strong proof of this. In fact, if I am not mistaken (I have not found a source), when various Hasidic sects in Europe wanted to differentiate themselves from other Hasidic sects, they would adopt strict rules of prohibition and permissibility, and that it is impossible to rely on the slaughter of Hasidic sects in this and that precisely to separate the two.
I asked you as someone who understands the “ultra-Orthodox” a little – is there really a dimension of pure halakhic study in all of the Haredi strictures (of course, the vast majority do) and then all of the rigid adoption of the strictures is really in place. Or, as I wrote, are there strictures whose entire essence is “to be concise” in order to differentiate themselves from Israeliness, and then it turns out that the Haredi faction that actually adopts those strictures is quite missing the point that these strictures are intended to prevent this faction itself.
