Joseph Sirois, a mess sergeant in Hawaii during World War Ⅱ, asked to be reduced in rank from sergeant to private so that he could be assigned to combat duty. In the Battle of Saipan in 1944, he manned a machine gun when the Japanese staged a strong counterattack. After the counterattack was stopped, the order to cease firing was issued. But Sirois kept firing at 10 enemy soldiers 300 yards away, and hit a few. His corporal began reprimanding him, but the commanding officer came over and congratulated him for a job well done.
The next day, Sirois volunteered to take part in the mopping-up operations. He found a foxhole with four Japanese crouched inside, and killed all four. Unfortunately, one bullet bounced back, hitting him in the knee.
第二次世界大戰期間，約瑟夫．西羅伊斯原在夏威夷任膳食軍士，卻要求降職為二等兵，以便上陣殺敵。一九四四年塞班島之役，日軍一度大舉反攻。西羅伊斯任機槍手，到日軍攻勢停止之後，仍然不理停火命令，向三百碼之外十個敵軍開火，擊中了幾個。他隸屬的陸軍下士責他不聽號令，但軍隊指揮官卻走過來，稱讚他做得好。
第二天，西羅伊斯請纓參與掃蕩行動。他找到一個散兵坑，裏面蹲着四個日軍，就把四人射殺。可惜一顆子彈反彈回來，擊中他膝蓋。
