In page Martial arts:
"Also during the 20th century, a number of martial arts were adapted for self-defense purposes and for military hand-to-hand combat. World War II combatives, KAPAP (1930s) and Krav Maga (1950s) in Israel, Systema in Soviet-era Russia, and Sanshou in the People's Republic of China are examples of such systems. The US military de-emphasized hand-to-hand combat training during the Cold War period, but revived it with the introduction of LINE in 1989.[citation needed]
