So I tinkered with this some more, swapped to large lasers to free up space for more (but still rather token) secondary weapons.
I also made a cruiser tank to go with it. I imagine this army operating in something like early world war II style, with the heavy tanks and infantry for the main force, and lighter, faster (but uncomfortably thin skinned) cruiser tanks being used as exploitation forces. Primitive battlemechs might operate alongside either group, depending on their mobility, but these are rare, harder to build (mostly purchased as surplus) and too prestigious to casually risk like you would a tank.
Their opponents would instead rely on a single tank hull (I'm seriously considering the scorpion, with a healthy number of variants) but have a larger force of primitive battlemechs to call upon, as they have better relations with the people who build battlemechs.
