In response to GrimmGunner:

Apart from Heroes and Fortifications, unit max squad sizes, and unit costs and upkeep, no unit stats nor weapons have been altered in any way. The Heavy Weapons Squad appearing to do little damage with its krak missiles against vehicles has also been confusing me since I haven't changed anything regarding weapon stats nor unit accuracy.

The only thing that comes to mind is if the "light tank" was in a squad of 2 or 3, which naturally increases their combined total hitpoints. If both the Heavy Weapons Squad and the light tank squad were fully upgraded to max squad size, theoretically the damage delt and damage received should be equal to if they were what they are unupgraded... though apparently that's not the case.

There is one caveat however: in vanilla Gladius the Heavy Weapons Squad comes with 4 "models" meaning 4 missile launchers are used when they attack. In my Tabletop Squad Sizes mod I reduced them to 3 "models" as per Tabletop and with this variant starting squads at minimum squad size, they start with 1 "model"... while this makes them weaker than vanilla Gladius even when fully upgraded, they do come with cheaper unit costs and upkeep.

I also adjusted the max squad size for Hive Crones from 3 to 2 and adjusted their unit costs and upkeep accordingly. My intention with vehicles and monstrous creatures here is to go for an Apocalypse style where you can field squads of vehicles... there's also the balance challenge to consider when you have for example a squad of 30 Ork Boys vs a single Space Marine Predator Annihilator...

Thanks for the quick reply. So as far as the heavy teams even when at the beginning of the game when it 1 vs 1 model the teams have very little damage, usually less than 1 point. And yeah i guess i will be going over to Drragen's mod to test out, re-scaling to codex does require some balance changes and as your intent is to leave it stock gladius I don't want to mess with your intent.
