It’s common for units at the National Training Center to split their Battalion Aid Station (BAS) into a Forward Aid Station (FAS) and a Main Aid Station (MAS). Unfortunately, many units find they don’t really know what to do with them once they’re split. Observers often find units asking the same questions; Is there a difference in capability? Is the MAS required to stay fixed, while the FAS bounds ahead? When does it make sense not to split the BAS? To answer these question, we must look at doctrine to clarify commonly misused terms, understand medical unit composition, and review tactics. These three steps will demonstrate that extended medical coverage and bounding medical coverage are useful techniques that units can use to increase survivability and treat wounded soldiers to get them back in the fight.
