What is "hukbalahap"

''' The Hukbalahap (, ), or Hukbong Laban sa Hapon (Anti-Japanese Army), was a Communist guerrilla movement formed by the peasant farmers of Central Luzon. They are popularly known simply as "Huks". They were originally formed to fight the Japanese, but extended their fight into a rebellion against the Philippine Government, known as the Hukbalahap Rebellion in 1946. It was finally put down through a series of reforms and military victories by Filipino President Ramon Magsaysay.
