Cool, I'll try out another skirmish on medium today.
It's been a few years since I was in my C&C prime in regards to the perfect build order, rushing, counterattacks, etc. But I think a few more tries and medium won't be too bad. Those fvcking NOD suicide infantry guys suck!
And what's with engineers not able to repair civilian buildings that you can garrison but become too damage? At the start of medium, I trained about 4-5 squads of riflemen and 4-5 missile squads ASAP to move them as far up to the civilian buildings in the center as possible. Garrisonned mixed infantry is excellent for keeping my base safe while I build up tech and resources. But it all gets destroyed pretty quickly from suicide guys and whatnot. I also try and get two predator tanks out ASAP so that they can move up and destory enemy garisson positions so my garrisonned buildings don't get busted up right away.
I think I should build a expansion base in the lower-right corner when I get built up to a tech center. When I noticed the computer doing that, it hurt me more since they had way more $$ and launched attacks through the center and from the top.
edit: I need to build more mammoths! I didn't realize they were so strong. In previous games, they were generally not worth the cost. And even here, they are very expensive, but seem almost unstoppable. I wonder if a single mammoth with railguns would win against two predator tanks with railguns? I would guess yes, though the mammoth is a little more than 2x the cost of a predator, but it might win by a larger margin to make the extra $300 worth it, but looks like it doesn't auto-heal until Elite.
