What code indicates departing Fillstand with a full unit?

• A. 10-15: Departing Fillstand with full unit
• B. 10-4: Acknowledged; will comply
• C. 10-10: Return to FSC
• D. 10-97: Arrived at scene/location

Answer: (A)

In patrol radio language, ten-codes convey what a unit is doing or their status. Departing a location with a full unit communicates that the unit is leaving a post or stand with all personnel assigned, heading to respond to calls or assignments. That specific code signals both movement from the current post and that the unit is complete and ready to operate together, which is important for accountability and coordination.

The other phrases describe different actions: acknowledging and agreeing to comply with a directive, returning to base, or arriving at a scene. None of those indicate the act of leaving a post with a full crew, which is why the code for departing the Fillstand with a full unit is the best choice.
