The expression originates in an anecdote often told to new conscripts in the
Israel Defence Forces; according to the apocryphal story, soldiers had been commanded by their superiors to assemble for a
loaded march with their weapons and ammunition vests. One soldier asked whether they should also bring their
kitbags. The reply was "good idea, bring the kitbag as well", to everyone else's annoyance. For if he had not asked, the commanders would never have thought to require bringing the kitbag. The expression began in Israeli army slang, then spread to Israeli society in general, and now has a limited degree of international use. ==Examples==
