Interesting little bit of trivia about the P-40, the IJAAF actually flew the P-40 in combat in Burma for the aerial defense of Rangoon.
"During the Spring 1943 Air Offensive in Burma, on March 21, 1943, a mission was flown against Feni Airfield by 21 heavy bombers (Sally II) and 15 fighters (Oscar II), the planes returning at night. The heavy bomber formation which headed toward Rangoon were fired upon by friendly anti-aircraft batteries around Rangoon, since the ground air defenses had not been properly alerted to the approach of the returning bombers which had changed the air base to which they were going to land.
'Not only that, but from Mingaladon Airfield, a unit of our forces equipped with captured P-40s took off to intercept. In the darkened sky, a tragic exchange of friendly fire took place. By the time they realized what had happened, some of the heavy bombers had force-landed after being hit by the friendly fire.'"

Another account of the action.
"12 aircraft of 12th Sentai and 9 of 98th Sentai, under escort from 15 fighters of 64th Sentai led by Capt. KUROE attacked Feni No.1 Airfield. Upon return, 98th Sentai and the 1st and 2nd Chutai of the 64th Sentai landed at Magwe. 12th Sentai and 3rd Chutai, 64th Sentai (directly led by KUROE) headed for Toungoo. But Toungoo was under attack from enemy aircraft at the time, and the formation was diverted to Hlegu. KUROE and his Oscars did not catch that radio message. They waited until the enemy raid was over and landed at Toungoo North. When 12th Sentai neared Hlegu, they were suddenly illuminated by searchlights and were attacked by fighters. The aircraft of 3rd Chutai Leader, Capt. Shigeo IWAHASHI, with sentai-cho Col. YOSHII onboard, was hit and crash-landed at Mingaladon. It hit an earth bank, broke its fuselage and the tail flew off. Four crewmen were killed in the crash and Capt. IWAHASHI and two others injured. Col. YOSHII was unhurt. Two other aircraft of IWAHASHI's formation were also hit and force-landed at Hlegu, but there were no casualties among the crew. The rest of the aircraft landed safely at Hlegu and Mingaladon.
The fighters which attacked IWAHASHI's formation were from a unit equipped with captured P-40s formed for the aerial defense of Rangoon."
