Scenario: Mae Sot
Date: 1942/01/21

After many deaths the Goverment orders cessation of all fighting against Japan and grants the Japanese Army free passage through Thailand. On January 21, Thailand signs an "assistance treaty" whereby Japan agrees to get back territories (in Burma and Malaya), that were ceded to Britain in 1909, in return for Thai military and other assistance. On the same day Japan mounts its main invasion of Burma. Also, on January 25, Thailand will declare war on Britain and the USA. 

The main Japanese assault is intially from around the area of the town of Rahaeng, through the border town of Mae Sot (after improving the road), then through the Kawkareik Pass in the Dawna Hills, with the objective being the Burmese coastal town of Moulmein. At this time the Japanese do not permit you to invade Burma itself, however you are ordered to provide support for the operation which may involve some fighting with local Burmese "Karen" tribesmen and British defenders around the Kawkareik Pass. 

Your specific orders are to protect the border north of the initial Japanese advance to Kawkareik. 

NOTE: While many Japanese troops are present on the battlefield, you do not command them so you cannot see them.
