If you have a Proxy engineer, is the G.Jumper considered a controller or is the Proxy Mk 1 the controller? Can one of the other proxies be part of a coordinated order?
Is this because G.jumper proxies are still each considered a trooper? They have the G.Jumper special skill so they count as 1 trooper despite each being their own trooper.
It's because the servant is equipment for the single proxy, that proxy becomes the controller. The other proxies are not controllers so can be part of a Co-order
