This is a comparison of the difficult situations facing two different American armies, one in the Philippines in 1941-1942 and the other in contemporary Europe, headquartered in Wiesbaden, Germany. Although there are many differences between the two situations confronting the two armies, there also are similarities. Both armies were understrength, consisting of about 30,000 US soldiers. Both operated in a resource-constrained environment. Both had to prepare to contend with large, aggressive powers in the region. Both armies were responsible for the defense of a broad regional expanse. The United States Army Forces in the Far East (USAFFE) ultimately were ill-prepared when the Japanese struck the Philippines on 8 December 1941. It is important that United States Army Europe (USAREUR) and its allies do not meet a fate similar to what their comrades in arms did in 1942.
