In 1944–45, Japanese "Teishin Shudan" ("Raiding Group") and "Giretsu" ("heroic") detachments made airborne assaults on Allied airfields in the Philippines, Marianas and Okinawa. The attacking forces varied in size from a few paratroopers to operations involving several companies. Due to the balance of forces concerned, these raids achieved little in the way of damage or casualties, and resulted in the destruction of the Japanese units concerned. Considering that there were no plans to extract these forces, and the reluctance to surrender by Japanese personnel during that era, they are often seen in the same light as "kamikaze" pilots of 1944–45.
