These will go out later, when there's a bit more to work with but for now, adopt these two changes:
* Units are destroyed when damage equals or exceeds HP totals.
This was inconsistent in the rules and honestly, inconsistent in my responses as well.
But ultimately, the intention is that a "standard" unit has 7 HP, hence equal or exceed puts them at the same level as standard Squadhammer units.
Plus, this way it matches how people expect things to work in an RPG.
* Support points now cannot be saved up from turn to turn.
This is an intentional change, to make them a bit more scarce.
