First, a request to everyone. If you're talking about an ambulance could you please say so? Because a "rescue" could be an ambulance, some sort of pickup truck or a 70,000 pound mutant fire truck with sixteen reciprocating saws onboard. It this case it might be one of those stupid "squmper" things. It's just another localism.
Now, please note the sections of the paragraph below I've highlighted through the use of bold text.
Oh, oh, I know, I know, let me answer!
Fire them all on the spot, then sell the ambulance to someone who might actually use it properly.
