Lost Armies?

[Fusilier]

Does anyone know of any "lost armies" besides the Chinese Nationalist's 93rd Division?

(At the conclusion of the Chinese Civil War in 1949, some remnants of the anti-communist Kuomintang (KMT) forces refused to surrender, including the 93rd Division. The division fought its way out of Yunnan in southwestern China, and its soldiers lived (fought as) nomadic lives in Burma's jungles before seeking asylum in Thailand. In exchange for their asylum, they fought for Thailand until 1982, helping to counter the communist insurgency at the Thai frontier. In reward, the Thai government granted citizenship to most of the KMT soldiers and their families.)

With troops marooned all over the world in Tw2000 (civgov in Yugo and 8th Army in Korea to name a few), I've been quite interested in making any comparisons with real world lost units. I don't mean deserters or small bands of men. I mean whole units. Is there any besides the 93rd Division?
