"In landing operations, retreat is impossible, to surrender is as ignoble as it is foolish. above all else remember that we as attackers have the initiative, we know exactly what we are going to do, while the enemy is ignorant of our intentions and can only parry our blows. We must retain this tremendous advantage by always attacking rapidly, ruthlessly, viciously, and without rest." - General George S. Patton, Jr.
Type 3 Medium Tank Chi-Nu (三式中戦車 チヌ San-shiki chusensha Chi-nu) was a medium tank of Imperial Japanese Army in World War II. It was an improved version of the Type 97 Chi-Ha line by giving it a Type 3 75 mm Tank Gun, one of the largest guns used on Japanese tanks during the war.
The Chi-Nu did not see combat during the war; they were retained for defence of the Japanese Home Islands in case of an Allied invasion.
Type 3 medium tank Chi-Nu was developed to cope with the American M4 Sherman after it was clear that the Type 1 Chi-He design was still inadequate. The Army Technical Bureau had been working on the Type 4 Chi-To medium tank as the counter to the M4 Sherman, but there were problems and delays in the program, and as a result a stopgap tank was required. Development on the Type 3 Chi-Nu started in May 1943 and was finished by October, just six months later. The low priority given to tank production by 1943 meant that the Type 3 did not actually enter production until 1944, by which time raw materials were in very short supply, and much of Japan's industrial infrastructure had been destroyed by American strategic bombing.
A total of 166 units were produced (55 units in 1944, 111 units in 1945). The Type 3 Chi-Nu was the last tank that was fielded by the Imperial Japanese armed forces, and was still being produced at the end of the war.
