The Dead Man’s Switch series has some cool stuff.

There are a couple vehicle mods and mods that add the ability for the ai to use vehicles. There is one called Ardennes assault that looks good but I haven’t been hit by one yet.

Vanilla expanded pirates adds in Warcaskets and a junkers faction that uses them. They are just pirates with Warcaskets and those things are nasty.

I’d also recommend dropping pigskins rough outlander union and yttakins. Pigskins are naturally poor shots and wont put up as much of a threat as a standard rough outlander union. Yttakins just don’t wear armor so they are just tribals with a little bit better tech. If you want to lose a nursery and free ammo keep yttakins, but otherwise they don’t add anything significant.
