You never know when that wartime experience will come in handy in the real world.

Take Lior Bregman, a former paratrooper with the Israeli defense force. Bregman, who helped set up a communications network that proved valuable in Israel's 1982 invasion of Lebanon, is now one of the most accurate pickers of takeover stocks in the arcane field of defense electronics and electronic warfare.
