Call me crazy but I think it'd be awesome if when you drove over dead bodies (only with Tank treads), they vanished, made a squishing sound, and left a pool of blood with some bone fragments in it. This idea was inspired by playing Men of War, where this is exactly what happens if a dead body is unlucky enough to get in the way of your vehicles. It's gross, it's violent, and I think it would fit great with the game. Maybe not the bone fragments if that's too extreme.

Also, if there was a 'threshold speed' value for when a vehicle can kill soldiers, that would be nice too; because in some mods (like the couple WW1 mods) the Tanks can't kill soldiers because they can't drive fast enough

Little morbid in my opinion, but it should be optional for certain.

Fair enough, but I think the 'speed threshold' as an option for modders would be great. Something that wouldn't affect the base game, and would enable slower vehicles to still run over soldiers in mods.

If squishing dead bodies were included, then you'd also need to include exploding headshots...
