You have to understand the department type that is in question. The EMS officers in these departments need to be at least an EMT because they are usually the ones who make the decisions related to equipment purchase and replacement, SOP development, provider oversight, PCR QA, EMS command in the field, etc. If they are not an EMT or active provider, how are they gonna be able to do the job? And secondly, without the proper credential, an officer making decisions they are not qualified to make will open up litigation should something go horribly wrong.
Plus, how can an officer be respected when they are only playing the part without having the credentials and experience of the people under them?
But it does say "Captain". And Captain is a front line, operations position... not administrative.
