Ok, im ama aware that the topics of QRS units and other similar topics have been discussed already, that being said, is there a way to tell which ems squads in the county are actually medics..and which are emt's?...i usually only notice a common one in my area which is medic 308(ply. ambulance)....that means they are actualy medics with knowledge of opening airways and defibriliators...and more ALS things right?...also, are the montco. QRS units the equivalent of an ALS chase car?....if the ambulance doesnt say "bls" on the side, can it still be assumed to be a "bls" unit?...i know "bls" and "als" carry different equipment. it is accurate to say that in montgomery county and the surrounding counties, the the term "chase car" refers to a QRS unit?..
