“All’s fair in love and war,” or so the saying goes. Resources are scarce on the battlefield, so captured equipment that is intact or requires only minor repair is sometimes pressed into service.
With supply lines stretched thin, this opportunism offers a way to replace badly damaged or destroyed equipment, such as AFVs. The down side to this equipment is that it can be difficult to maintain. Your Platoon’s mechanic is likely unfamiliar with the design, any captured manuals are in a foreign language, and replacement parts are only available through salvaging other wrecks, capturing a supply depot, or fabricating them in the field.
