Again, Bad assumption. The troops I am most familiar with are:

the Co Cdr, an assistant US DA in NYC when not deployed

the Platoon sergeants, who are 1) a NYC police interrogator, 2) a NYC police SWAT leader, and 3) a NY Arson investigator.

The troops that make up the unit in question are mostly NYPD, NYFD, and NY EMS, hardly "19 y/o kids from Iowa".
