Personally for lvl 20-40/50, I would recommend the mortar truck with it's HE atatck or Rocket truck's Triple strike (though personally I like triple strike better). They're really helpfull.

The Heavy tank is also a good cannon fodder (as well as having a cannon of it's own) if you can afford those gears. Though peace keeper is better for tanking.

Troopers remain the best occupationalist before wimps and equally levled grenaiders with a few researched upgrades are great too.
