1) Game itself does not have 'light tractor' properties for vehicles. Game has just 'tractor' properties.So in your suggestion unarmed Kubelwagen can move Morser 18 howitzer. Realistic as I think )).

2)Oficer of each nation in #valour mod spawns with unarmed vehicle:

USSR - Gaz-67command version
USA - Willys command version
UK - Willys command version
France - Laffly v15t
Poland - Polski Fiat 508
Greece - Polski Fiat 508
Germany - Kubel command version
Japan - Type95 command version
Hungary - Kubel command version
Romania - Kubel command version
Finland - Kubel command version
Italy - Fiat 508cm
China - Ford mod.1933
Bulgaria - Fiat 508cm
Netherlands - Laffly v15t
N.Korea - Gaz-67command version

Did you check this?

Aye, I did check it, and am fully aware that officers spawn with an unarmed light vehicle. My suggestion was that the unarmed light vehicles also be made available in the transport tab, alongside the trucks, like how Italy has the Fiat 508cm, and Poland the Polski-Fiat 508. So, for example, when playing as USA you could spawn an unarmed Jeep, which would be cheap and useful for, say quickly moving a bazooka team to where it is needed, or with China you could spawn a GAZ-A or Ford Model 1933 to move a fuel drum from a supply truck to a tank at the front, thus posing a smaller target than moving the whole supply truck.

I agree - a Kubel towing a Morser would be unrealistic. If the game has no 'light tractor' properties then it's fair that light vehicles cannot tow guns. Although the Willys MB can - is that a bug?

Also, I have another suggestion, just an idea so if you disagree then nevermind, but the Kettenkrad was designed as a tractor, and could actually tow heavier loads through mud than most German trucks. If the Opel Blitz can tow a Morser 18, I'd say a Kettenkrad should be able to as well.

Final point - the Laffly v15t can only hold two people, but has seats for four - I believe this is a bug.

Again, big fan of #valour, and hope to see it progress :)
