Sentry drone gun

The Sentry drone gun is a USA upgrade for the sentry drone, equipping it with a 20mm autocannon. This makes the Sentry Drone highly effective at tracking down and destroying stealthed enemy infantry, such as Black Lotus.

The Sentry drone gun upgrade is available from the American war factory.

Trivia

 * The 20mm autocannon itself resembles the M85 .50 calibre AFV turret-mounted heavy machine gun due to the distinct heat shield and flash-suppressor. However the size and length of the gun do not correspond to the actual real-life M85, perhaps hinting that it is an auto-cannon with certain elements taken from the M85.
