Looking for ID of the first vehicle with the tracks

I believe both of the first two photos show French vehicles.

In the first one, I think the truck is a Laffly, model unknown and I do not presently know the make of the bus either. It is remotely possible the truck may be some sort of Berliet also.

In the second photo, I believe the truck is also a Laffly.

As to the armoured vehicles, I have no clue as that is not my area of interest.

In the first photo, I think they may be from the French Air Force depending on the roundels on the sides of the vehicles.
