sounds to me like if you wanted to slow down the destrction of a city you could defect to the country of the attackers, bail out over city & whenever attackers (now countrymen) bombed, they would die due to killshooter.
I see how this could suck real fast, & is another good reason for personna non grata (no ammo, cause ya killed countrymen). Of course anyone who actually did this would be considered quite offensive & would largely be considered a person who needs a real life........
