The βCourierβ has not been as active on the front since losing its Starlink connection.
This UGV is apparently controlled by a fiber-optic cable, with radio backup if the cable fails.

Radio control of a UGV (Unmanned Ground Vehicle) is literally its weak link because line of sight is difficult to maintain.
Fiber optic cable on a spool now being used to control some FPV drones could solve this problem.
It would also make the vehicle immune to jamming.
