The game is set in 1999. In that year, vehicle-bourne rocket launchers included anti-tank guided missiles like TOW, Kornet, Spike, Javelin. Some like Javelin were also man-portable.
To reflect the state of human technology in 1999, the rocket tank should be able to fire guided rockets and the man-portable rocket launcher also.
Perhaps the HWP rockets could have 5 waypoints and the man-portable rocket launcher could have 3 so it is still inferior in guidance to the 9-waypoint alien blaster.
