MW,
1. Rav Avraham Shapira and Rav Shaul Yisraeli were alive until a few years ago. Is that “now” enough for you? How about Rav Dov Lior? He is still alive (until 120). Ditto Rav Shmuel Eliahu.
2. FYI, I live in a settlement in the Binyamin area.
3. The above mitzva is incumbent on Klal Yisrael not on any individual. As I am nichba bakeilim I am waiting for the IDF or the Shabach to demand my services.
