You can't rush Easy8 call-ins.
Well I guess you could by throwing your troops at the enemy constantly so you can boost the CP gain with non-stop fighting...but either way you'd probably have enough fuel for an E8 in addition to the Captain if you got an even share of the map by the time you had enough CP.
(If that was a joke, I'm afraid I didn't find it very funny)
Easy 8 arrives too late and is far to Mediocre at its job. I like the Standard Sherman better. Its job? Kill Infantry and Spot. Does it Well
Easy 8? Kill tanks sorta...does it sorta....also sorta kills infantry...sorta...
I rush Shermans I wouldnt even want to rush Easy 8s. Thats almost as bad as trying to Rush a Jackson...almost...
