This is a wild exaggeration - very few people are a good fit for serving in a military, and while the Israeli army ignores that, and drafts many it shouldn't (resulting in high suicide rates on one hand, and alleged war crimes on the other), it still only drafts ~69% of AMAB and 55% AFAB.

It does gives free technical education and experience for some recruits (not necessarily the top, and that experience isn't always teh best), but of course that affects tech employment - you'd see higher rates of service across tech employees, as that service gave them a jump start on their tech education.

That said, even if the Israeli military decides to draft a person, that person can stand up and refuse. It ain't "free" (may result in imprisonment,) but it's a choice that even if too few make, it is one, and making it is a strong signal about what kind of person they are.

These people are from an intelligence agency, not just army.
