6. Never take the third light from a match, it's bad luck. 不能用同一根火柴點(diǎn)3次火

In World War I, snipers sometimes operated at night. Their technique involved waiting for someone to strike a match to light a cigarette; on spotting the light they'd train a scope on them. On the second light, the sniper would focus his shot, zooming in ready for the kill, on the third light, he would fire, killing the person who lit the match.

在一戰(zhàn)期間，狙擊手通常在夜晚作案。他們的作案技巧就是等有人點(diǎn)煙。第一次點(diǎn)煙時(shí)狙擊手可以確定方位；點(diǎn)第二根時(shí)狙擊手瞄準(zhǔn)準(zhǔn)備射殺；點(diǎn)第三根煙時(shí)，他就開火將點(diǎn)火之人打死。
