Even in Israel, the number of actual strikes a fighter does has got to be pretty small. They just aren't bombing the crap out of the occupied territories that much, and they haven't had one of the IAF's legendary air-to-air fights in a number of years.
Like P73 said, assault support works every day delivering beans, bullets, and band-aids, and they probably are inserting patrols and such on a regular basis. Plus, those times that Israel does a strike in it's territories, is frequently is a Hellfire fired from an AH-64.
