Walkthrough Gamm meant as a joke.8

[Schwager1]

I have tried this 10 times with no success. I gather that the walk through that says " This mission is easy " is meant as a joke, since the research to clean the computer takes 20 minutes & the missile codes research has 3 steps. I am either approaching this mission wrong or I didn't complete an earlier one correctly. Anyone have a suggestion?

do you have enough power?, you need to balance out between researching and making tanks
