The video today from the NHK collection, dated October 26, 1944, features an assortment of aircraft but prominently Mitsubishi G4M2Aa or Ab belonging to the 762 Kokutai. The unit was organized on February 15, 1944 in Hsinchu, Taiwan as a "Betty" unit but it was reorganized on July 10 with four "kogegi hikotai" (attack air units). The 3rd Kogeki Hikotai was equipped with Yokosuka D4Y "Suisei", the  405 and 406 Kogeki Hikotai had Yokosuka P1Y "Ginga" and the 708 Kogeki Hikotai had "Betty" and "Ginga". On October 10 the "T Kogeki Butai" ("T" attack unit) was organized to take part in the Taiwan air battles from October 12 until 16 and later in the Philippines. October 12 is mentioned in the video narration as the date the "Betty" attack is beginning. Note the "Betty" with the "K 762-33" tail marking. The 762Ku used the "762" as the unit marking for their "Betty" bombers but also "62-".
