Armored Personnel Carriers (APC) were military vehicles used first by the New United States and then the United States of Europe. They were originally up-time coal mining trucks: construction vehicles of greater than ordinary size and capacity with thick walled dump beds and thick heavy duty man-high tires. After being transferred back in time, the people of Grantville modified their trucks with armor-plated shutters over the windows and rifle slits in the beds.
The immense size and mobility of the APCs were without equal in the 17th century, and proved quite decisive at nearly every engagement the NUS was involved in from 1631-1632.
Six APCs were used during the invasion of Saxony and Poland. While initially successful, bad weather slowed the advance of the vehicles, which left them out of action. This allowed the Poles to capture one of the APCs. As of the beggining of the summer of 1636 one of the APC's has been captured by Polish Forces occupying the city of Poznan. The Polish army has shown an interest in reverse engineering the APC.
