These are the BSPP's advanced life support ambulances, with a larger rear working interior copartmen than the Renault Master vans which are used as BLS units. This type constitutes around fifteen percent of the total fleet of some 140 units - plus 115 or so of BSPP's unique combination BLS ambulance and light pumper "first aid" (PS) trucks. Both of these other types are pictured on this site.
