Lipkin-Shahak was the only Ramatkal that you could say that of; he always had a low key, calm, intelligent, attentive, demeanor about him. He did not exude that excessively macho charisma or "power" that most senior officers still do (it gets toned down as they climb the ranks), but there was no doubt who was in charge.
With that, I think he epitioised the naive general who became a politician, thinking that the political world was the same as the hierarchal army was, & that competence & calm logic would win, or that it would vanquish-or even converse logically- with political crazies. Israel's loss. z"l
