For the actual charge value of their melee weapons (which should be a lot higher), one has to find the units in question in the EDU and look up the values associated with their secondary weapons.
Should the charge value of 1 be assigned to the secondary weapons of these units and if you have taken said value from the EDU already, I apologize for my incorrect assumptions.
