X and Y are map coordinates and the speed is in pixels per frame (1 second = 30 frames). Queued movements go into a queue and are processed one at a time.

# Picks a random unit then goes there at 4 pixels per frame. 
# Once it has arrived, it picks another random unit and moves there at one pixel per frame.
