Permission: cad.unit.self. Also needs an active staff profile. Needs a signed-in user; service credentials are refused with USER_REQUIRED.
Access: Browser session only.
Starts a unit with the caller as its first crew member. The unit is AVAILABLE. An existing off-duty, empty unit with the same callsign is reused when its agency and type match. Records UNIT_BOOKED_ON and CREW_JOINED.
A user can crew one unit at a time.
