"Welded on spare tracks" armour in-game

[Mobhack]

Patton banned the practice in his units, as he considered it strained the engines and slowed them down, so consider deducting 1 speed point, if there is more than a token amount.

Feel free to do it to taste in a scenario.

It was likely only of use for morale purposes - and Patton probably had a good point on the practice. So maybe nil effect on armour, -1 speed +3 or so morale?
