Human Factors
We were on a visual approach; on about a 5 NM right base. I was flying; Captain was pilot not flying. As we were flying on the approach; the Captain suddenly noticed a small flying object which he later described as a camouflage painted UAV; due to his experience in the military with them; it was easily identifiable for him. I never saw the UAV; nor got any TCAS TA or RA; as they do not show up. He notified ATC as soon as practicable and safely within our FOM guidelines. I continued on with the approach and landed as normal. We did not encounter any damage because of the UAV as it wasn't in our flight path I believe. I'm not sure why the event occurred. I can only guess it was poor planning and communication between the Control Tower at ZZZ airport and the military entity operating the UAV.
