"Our politic comes out from the barrel of our guns". Mao Zedong
Mao in his entire life published 4 books. All 4 books had been translated to Farsi.  His main idea has been crystallized in a thick book by the name of "4 philosophical essay".He classifies the combats into 2 different categories.
1. Strategy
2. Tactics.
  These concepts were implemented by Fadaeyan in Syakal during shah days.  Syahkal is a area of Gilan providence in northern Iran.  It is located close to Caspian sea by Russian border. There is a fine line between Maoism and terrorism. Mao described combat between oppositions of unequal strength with overly armed enemies as tactic. He also describes gurrila warfare along with political propaganda in a long run achieves poltical objectivity which he calls "strategy".   Attack and withdraw is intended to break large group of enemy. Mao emphasis that combination of guerrilla warfare with propaganda and political influences leads to revolution in a long run.  Mao's view about revolution is distinctively differed from Marx or Lenin.  In order the revolution develops, Marx emphasis on 2 components which are basics.  
A. poverty   
B. Mass awareness of the poverty.  
     Marx believed poverty alone doesn't lead to revolution. Awareness of the source of poverty is necessary to create social revolt. on the other hand, Lenin also believed the revolution happens when 
A. The top, ruling class, can NOT rule 
B. The bottom, mass,  can NOT cop.  
      There is nothing about "guerrilla warfare"  in Marx or Lenin manuscripts.  2 brothers Ahmadzadeh were founders of communist party Fadaeyan in Iran. They summarized Mao's guerrilla warfare into Farsi. They also attended in Syahkal guerrilla combats during shah days. They both were arrested and executed by Royal court in 1971.  They engaged in Mao's model of warfare in Syahkal. Their father became governor of Khorasan right after revolution but his governmental position didn't last that long and he was being dismissed.  Mao's destructive ideas could be seen on Amir Parviz pooyan write ups. He was also one of the founders of Fadaeyan communist organization. Pooyan committed suicide in his residence when the house was surrounded by shah secret police SAVAK. SAVAK found his dead body on the floor. Apparently, he took his own life before he get arrested. Pooyan, In his main book,  "the necessity of armed warfare" divides socio political context of Iran into 2 hemispheres. 
A. ruling class which was shah and  his administration.
B.  hopeless mass which don't see themselves as be able to overthrown monarchy. Pooyan saw shah and his administration as " Absolute invincible" (خدشه ناا پزیری مطلق on the other hand, Iranian people "Absolute inable" ( ناا توانائ مطلق) are the terms he uses in his paperback book. He believed just through gurrila warfare could teach to Iranians that Shah and his admininstration are vuneralbe and could be defeated. Gurrila warfare open the path between disable Mass and powerful establishment. On striking contrast, Marx never sees working class as "absolute disable"as pooyan was conceptualizing in his book. Marx viewed working class as powerful and vibrant force which eventually takes over the establishement and enforce it's own hegemony. He calls it "Dictatorship of proletariat".   Pooyan was seeing Monarchy  as a forceful, dominant establishment that only guerrilla warfare can make it vulnerable and open the path toward revelution.  In his paperback book, he teaches guerrilla warfare as the only way to topple monarchy.  Mao's idea had great impact on founders of Mojahedin Khalq organization Hanif Nejad, Bade zadegan and Khiabani. Founders of Mojahedin (MEK) chose Mao's gullila warfare as a way of combat with establishment of Monarchy.They believed gurrila warfare is effective way of dealing with dominant,  powerful shah's army.  Mao's influence in Iranian culture goes further. The movie maker Masood Kimiaie was apparently deeply impressed by Mao's.  In his famous movie "The Deers"(, گوزنها) Kimiaie shows the revolutionary man who is injured take a refuge in his childhood friend (Sayyed). Sayyed is a drug addict. All the sudden Sayyed became a revolutionary man. According to Marx, drug addicts are "Lumpen proletariat". Lumpen proletariat is a class of society that plays 2 sides throughout history. Some Lumpens take a side with ruling class such as Shaboon Jafari  in 1953. Some Lumpen take a side with mass such as Tayyeb Haj Rezie in 1963.  However, Marx never consider Lumpen Proletaria as a vibrant revolutionary political figures. He emphasis on workers, tabours as the main forces of revolution. In the movie "The Deers" kimiaie, influenced by Mao,  shows Lumpen proletariat became revoutionary individual who fianlly get shot and killed when police raided his residence in southern Tehran.  Again, Mao was talking in the movie.  The movie and it's scenario had nothing to do with Marxist Leninist.  It was all extracted from terrorist, adventurous Mao's mind.  The main point is that non of these idea had anything to do with Marx or Lenin or socialism.  It  was all Mao's mind set.
