I've tried to make this mod:
crafts:
- type: STR_AVENGER
deployment:
- [4, 11, 1, 0]
- [5, 11, 1, 0]
- [4, 12, 1, 0]
- [5, 12, 1, 0]
- [4, 13, 1, 0]
- [5, 13, 1, 0]
- [4, 14, 1, 0]
- [5, 14, 1, 0]
- [4, 15, 1, 0]
- [5, 15, 1, 0]
- [4, 16, 1, 0]
- [5, 16, 1, 0]
- [4, 9, 1, 0]
- [5, 9, 1, 0]
- [4, 10, 1, 0]
- [5, 10, 1, 0]
- [3, 10, 1, 0]
- [3, 11, 1, 0]
- [3, 12, 1, 0]
- [3, 13, 1, 0]
- [3, 14, 1, 0]
- [6, 10, 1, 0]
- [6, 11, 1, 0]
- [6, 12, 1, 0]
- [6, 13, 1, 0]
- [6, 14, 1, 0]
But it has no effect - the tank still start in the first slot, blocking the exit ramp (and making smoking duty on turn one VERY problematic)
