Did you ever loose a few Construction Robots during an alien base raid with your tank?
Now the hassle is over!
Just toss them inside the trunk alongside with some repair packs and you are ready to go!

Pros:
- Vanilla friendly!
- drones repair tanks and cars during combat while they are safe inside the trunk!
- the maximum repair rate is blazing +25 hp/sec
- other means of repair will speed up the process

Cons:
- it only works if the vehicle is in your area of influence (20 tile radius)
- you need 250 construction robots to achieve the maximum repair rate
- yes, that means 1 robot will have +0,1 hp/sec restored
- your drones blow up alongside with your tank if you fail to keep it alive

Prepare for happy destruction time!
