Actually I think (with Eagions skills) the Goliath could become a team-weapon with a 3-man crew (1-man needed to crew the team-weapon). The crew would move with the goliath all bunched up (close formation like an HMG team). The goliath would be deactive (non detonateable), when you want to detonate the Goliath the player has to toggle deploy the goliath which makes the crew immobile and the Goliath mobile for "x range".
This is more of an realism mod kind of thingy, I actually like having the goliath as mobile unit.
I tried this idea for a bit. The game can get a bit buggy with using team weapons. There are of course no crew markers for the Goliath. Lets take the MG42 for example. If you remove the crew roles actually man the MG the squad will treat the MG as its own model like showing 5 instead of 4 in the decorator. If that model goes down, reinforcing also bugs out. For making the 'crew' stationary and Goliath free movement. I do not see a way to tether a unit like this. Maybe a movement speed aura if it goes out of range but either it would come to a dead stop and can not come back or it can still creep away.
With small variations to the previous showing. This is the outcome.
The Goliath is apart of the squad. Once the order is given it will charge and detonate. Pathing could be adjusted with better turn rates. The Goliath can be reinforced by any reinforce point, for munitions of course. The unit can still retreat though I may need to relook at the speed/posture modifiers for this unit because the Goliath does lag behind. If you want to take a closer look at the two abilities, My mod has been updated. The Goliath from the vehicle is available to the opel blitz with the Feursturm doctrine and the Goliath squad is available to the Overwatch Doctrine. I am expecting a lot of bugs, primarily if there are two Goliath on the field.
