China deployed these suicide units against the Japanese during the Second Sino-Japanese War. "Dare to Die" troops were used by warlords in their armies to conduct suicide attacks. "Dare to Die" corps continued to be used in the Chinese military. The Kuomintang used one to put down an insurrection in Canton. Many women joined them in addition to men to achieve martyrdom against China's opponents. A "dare to die corps" was effectively used against Japanese units at the Battle of Taierzhuang. They used swords. Suicide bombing was also used against the Japanese. A Chinese soldier detonated a grenade vest and killed 20 Japanese soldiers at Sihang Warehouse. Chinese troops strapped explosives like grenade packs or dynamite to their bodies and threw themselves under Japanese tanks to blow them up. This tactic was used during the Battle of Shanghai, where a Chinese suicide bomber stopped a Japanese tank column by exploding himself beneath the lead tank, and at the Battle of Taierzhuang where dynamite and grenades were strapped on by Chinese troops who rushed at Japanese tanks and blew themselves up. In one incident at Taierzhuang, Chinese suicide bombers obliterated four Japanese tanks with grenade bundles. During the Chinese Civil War the National Revolutionary Army (NRA) was known to have used penal battalions from 1945 to 1949. A unit made up of deserters and those accused of cowardice, the penal battalion was giving such tasks as scouting ahead of the main forces to check for ambushes, crossing rivers and torrents to see whether they were fordable, and walking across unmapped minefields. The military was formed through bloody and inhumane conscription campaigns. These are described by Rudolph Rummel as: This was a deadly affair in which men were kidnapped for the army, rounded up indiscriminately by press-gangs or army units among those on the roads or in the towns and villages, or otherwise gathered together. Many men, some the very young and old, were killed resisting or trying to escape. Once collected, they would be roped or chained together and marched, with little food or water, long distances to camp. They often died or were killed along the way, sometimes less than 50 percent reaching camp alive. Then recruit camp was no better, with hospitals resembling Nazi concentration camps like Buchenwald. For regular provincial Chinese divisions the standard rifles were the Hanyang 88 (copy of Gewehr 88). Central army divisions were typically equipped with the Chiang Kai-shek rifle and other Mauser type rifles from Germany, Belgium and Czechoslovakia.
