Interesting. Why would that be?
Part of it is just time frame, that Israel’s such a young country that they haven’t had much time to develop military pomp and formality, while reverence for guerillas and irregulars and swashbuckling raiders like Ariel Sharon’s parachute battalion, no sticklers for ceremony, are fresh in the mind. Beyond that, the Israeli military has long been individualistic and less rigidly hierarchical in ways that to foreigners might suggest indiscipline or insubordination, but in fact do not compromise combat ability or effectiveness. And I’m sure that the fact that most Israeli young people must spend some of their salad days in the military (universal draft) promotes the idea that they should be able to enjoy themselves, and be free from non-essential discipline and formality, as much as possible while defending their country.
