Five levels of veterancy is what makes volks so problematic. Combined with how AT weapons confer a great deal of XP, often ramping up that XP gain, an extremely cheap unit can became a highly vetted powerhouse rather quickly.
5 vets that means jack shit you mean. Im getting a bit tired of ignorant people continually proclaiming that vet 5 on volks is potent while in reality a vet 3 riflesquad would wipe the fucking floor with them.
