Ben Levi,
There are two different categories that need to be clarified. There are Gedolim that hold that all Yeshivaleit should be drafted:
Rav Sholom Yofef Zevin Z”TL
Rav Aharon Lichtenstein Shlita
Rav Shlomo Aviner Shlita
There are then many more that hold Talmidei Chachomim should not be drafted but those that are not on that level should be drafted (and Yeshiva students could delay being drafted but should eventually serve):
Rav Avraham Yitzchak Hakohen Kook Z”TL
Rav Yehuda Amital Z”TL
Rav Tzvi Yehuda Kook Z”TL
Rav She’ar Yoshuv Cohen Z”TL
I am not particularly familiar with the Mizrachi/Hesder world, so I would guess that there are many more whom I am not familiar with.
