Sure, if you manage to assassinate the entire command chain, things will go pear shaped.

I dare say you could likely assassinate half the command chain, and the military will still managed to get where they need to be, when they need to be there. Military command chains have levels of redundancy that civilian organisations wouldn't dream of.

As a concrete example, it's estimated that the British lost ~40% of their officers in the Battle of Albuera, and they still managed to repel Napolean's forces.
