(Marshal of the Republic)
Taewŏnsu (대원수; literally grand marshal, usually translated as generalissimo) is the highest possible military rank of North Korea and is intended to be an honorific title for Kim Il-sung, Kim Jong-il and Kim Jong-un. The rank is senior to that of Wonsu. The title also exists in Chinese military history as dàyuánshuài (same Sino-Korean characters 大元帥), and was briefly taken by Sun Yat-sen.
The rank of taewŏnsu was created by a joint decision of the Central Committee and Central Military Commission of the Workers' Party of Korea, the National Defence Commission and the Central People's Committee in April 1992 to honor Kim Il-sung on his 80th birthday (Day of the Sun). In February 2012, his son and successor Kim Jong-il was awarded the title posthumously on the occasion of his official 70th birthday (Day of the Shining Star).  On a new official portrait unveiled on 7th January 2021, Kim Jong-un appeared to wear the taewŏnsu shoulder boards on his military uniform, showing that he had promoted to the rank at some point prior. 
The insignia for taewŏnsu is similar to wonsu but with an added crest worn beneath the shoulder board's large marshal star (and an added crest added to the parade uniform's marshal star worn below the collar), below the Emblem of North Korea. The rank insignia is based on the unofficial rank Generalissimus of the Soviet Union.
If translated, the full rank is "Grand Marshal of the Democratic People's Republic of Korea" literally and "Generalissimo of the DPRK" in the usual translation.
According to rank comparison charts of the United States Forces Korea (USFK), taewŏnsu is equivalent to a "seven-star general", with the junior ranks of wonsu and chasu listed as six and five stars respectively. The rank is frequently referred to in U.S. military publications as "grand marshal", comparable to the rank of general of the armies although that is normally considered a six-star rank[by whom?]. European military texts rate the rank equivalent to a generalissimo.
The South Korean armed forces have never made an attempt to declare an equivalent to the wonsu ranks of North Korea, and indeed often deride these ranks as having been created so as to "outrank" the military leaders of other nations, rather than for any necessary purpose of military administration. Even so, the holders of these ranks have commanded one of the largest military forces in the Pan-Asian theater therefore giving some credence to their existence.
