As promised, we have just published the technical codex over on Wargames vault.
It contains additional rules to allow you to customise your units, as well as including additional assets in your force.
The Technical codex includes specialist personnel, (including combat medic, artillery observers and journalists) special rules (including tank hunters, police and intoxicated units) and infantry and vehicle equipment (including specialist munitions, command detonated mines and v-shaped hulls).
The Technical codex will be updated to incorporate new unit rules when they are written.
We are aiming to publish the unit designer as soon as possible.
Edit: We have obviously failed to get the unit builder out in the timeframe anticipated. Current estimate is for September. Apologies for the delay.
