Sgt. Kayla Medawar is played by Kavita Patil. Reporting directly to Colonel Ryan, Medawar works in the incident room under the callsign 'Dog Patch'.  She is responsible for field intelligence and communications, and occasionally serves as an inter-department liason when the Unit requires extra support.

Sgt. Medawar is almost unshakeable, remaining cool and professional even when a mission is falling apart around her.  She has never been seen to raise her voice in anger, even when the Command Center is in a shambles following an explosion early in the third season and the repair team is slow to restore communications.

Virtually nothing is known about her personal life; she only appears in the Incident Room, and then only in a professional capacity.
