[Rules] Commandeering an enemy truck?

[Schoenwulf]

3rd Edition: 5.31 Harmless Enemies
A unit may freely enter and exit hexes containing only enemy leaders (see 6.71 for possible leader casualties) and/or unarmed, empty enemy trucks, wagons or sledges. Such enemy transports are eliminated if the moving unit is a combat unit. Unarmed, empty transports can freely enter hexes containing only enemy unarmed, empty transports. They have no effect on each other.

4th Edition: 5.31 Harmless Enemies
A unit may freely enter and exit hexes containing only enemy leaders (see 6.71 for possible leader casualties) and/or unarmed enemy trucks, wagons or sledges. Such enemy transports are eliminated if the moving unit is a combat unit. Unarmed transports can freely enter hexes containing only enemy unarmed transports. They have no effect on each other.

Seems like the only difference is the removal of empty in three places.

Just seems a shame not to use a perfectly good truck that someone left the keys in.....must be my Chicago youth background!
