M3 Half-track
The Carrier, Personnel Half-track M3 was an armored vehicle used by the United States, the British Empire and the other Allies during World War II and the Cold War. Nearly 43,000 were produced, and supplied to the U.S. Army and Marines, as well as British Commonwealth and Soviet Red Army forces, serving on all fronts throughout the war.
Between the world wars, the US Army sought to improve the tactical mobility of its forces. With the goal of finding a high-mobility infantry vehicle, the Ordnance Department had evaluated the half-track design by testing French Citroën-Kégresse vehicles. The White Motor Company produced a prototype halftrack using their own chassis and the body of the M3 Scout Car.
The design, using as many commercial components as possible to improve reliability and speed production, was standardized in 1940 and built by the Autocar Company, Diamond T Motor Company, and the White Company.

No entiendo muy bien qué busca. En la carretera no tiene bonificaciones defensivas, y mis hombres son los que les están emboscando a ellos. No sé si es un patrón a base de scripts, no sé, lo unico que sé es que actuo en consecuencia del comportamiento del enemigo.
