+// function name: armatak_fnc_send_uas_video_cot
+// function author: Valmo / ArmaTAK contributors
+// function description:
+//   Sends a b-i-v CoT event that declares the RTSP video endpoint for a drone.
+//   The ATAK UAS Tool picks this up and shows the drone in its UAS list with
+//   the associated video feed available for playback.
+//
+//   The drone entity MUST have the variable "armatak_attribute_video_url" set
+//   to a valid RTSP URL, e.g.:
+//       _drone setVariable ["armatak_attribute_video_url", "rtsp://192.168.1.10:8554/live/drone1"];
+//   or via the 3DEN attribute "Video URL (RTSP)" in the ARMA Team Awareness Kit
+//   attribute category.
+//
+//   If the variable is absent or empty the function exits silently.
+//
+// Arguments:
+//   0: _drone <OBJECT>  The drone object.
+//
+// Return value: none
