Honestly, the greatest weakness of the military right now is ground troops. If you want people to be willing to die, you have to give them a cause to fight for, and discounted college tuition is not going to do it.

That's why the US' military is built around high tech and low casualties, because, after Vietnam, they realized Americans aren't willing to bleed for Empire, and that's why Ansarullah are cleaning up against Saudi Arabia, because nobody wants to die for a corrupt monarchy.

The solution to this problem is AI murderdogs.
