How did Israel manage for decades to have everyone convinced they had one of the most capable and professional militaries on Earth? A 20 year old Major, that isn’t even old enough for most people to have acquired a 4 year university degree. It’s literally impossible to end up a Major at age 20 in pretty much every professional military on earth.

For fks sake, officers often are required to have a 4 year university degree to get their first commission and start out something equivalent to 2nd lieutenant. Even when there is a national draft and a military is filled with conscripts, you tend to see the enlisted have a bit of rank inflation but commissioned officers tend to be older due to the education requirements.
