Although the profile mentions that Sinatra's character and his fellow agents are members of the OSS, this could use some elaboration. This movie is clearly an attempt to dramatize certain portions of OSS Detachment 101's exploits in the CBI during WWII. This is the only film I've ever seen that deals with a story involving the OSS that is based on any sort of factual series of events. Detachment 101, formed very early in WWII as an OSS Operations Group (OG), was responsible for hamstringing Japanese operations in the China-Burma-India (CBI) theater along with the Kachin Rangers, native people whom they had trained and equipped and a host of other Allied special operations type units, many of which contributed to the lineages of later special ops units, especially in the US (Merrill's Marauders = 75th Ranger Regiment and Det. 101 being the root of lineages of both CIA covert operations units and Army Special Forces).
The story which most clearly sticks out here is the episode involving the discovery of warrants issued by the Chinese Nationalist government authorizing local bandit warlords to confiscate goods from anyone, including Allied forces. Although not quite right in the movie, these bandits attacked a group of Kachins, which brought the attention of US OSS agents. These agents, with their Kachin Rangers, attacked across the Chinese border, discovered the warrants and almost caused a major diplomatic incident between the US and Chinese governments, especially after the OSS agents turned a blind eye to the execution of the Chinese bandits by Kachin Rangers.
All in all, not a spectacular film and the love interest aspect a little odd in the middle of a war-zone, but still notable as the only film dealing with the subject of OSS OGs in a semi-factual way.
