Why didn't you use Detriev? He looks pretty kewl!

I find it rather easy to defend against allies. All you need is to put Boris (get him elite if you want) in a CSC with whatever other two infantry units you like, and that's a great defense right there. Most country specific units can be used to defend really well too (Iron Dragon anyone? Focus Tank? Tesla Tank?).

Indeed, Volkov can go in the CSC.

If you not only spied all 3 battle labs, but also owned Yuri's tech tree, you can have 2 Volkovs and Boris in the CSC if you want, which is total ownage and is practically unstoppable. The only way to kill that combo is a WHOLE lot of air units .

I usually play as Soviets as North Korea or Iraq, and if possible a map with water. I love naval wars.

1) Deploy Conyard
2) Build Tesla Reactor, Barracks, and Ref. While ref is being build, I put walls around my Conyard (Seals like to swim in and blow it up).
3) Make sure my miner is mining the front of the ore patch, not the back like they like to do, and build War Factory.
4) Build a few halftracks (5 at this point, 5 after I get Industrial plant) and a miner.
5) Build radar, an extra reactor, battle lab, industrial plant, a few miners, palace.
6) Build air field and get 4 MIGs. Spy the enemy if possible.
7) Centurion comes in play, along with Boris, a flak trooper and a desolator, or two desolators, that depends. I actually think Boris and two tesla troopers would be better now that I think about it though...
8) Iron Dragons or Focus Tanks.
9) If possible, a navy of about 10 subs, 5 Dreadnaughts, and 5 Akulas.

If you get to this point you can win quite easily. Make a few Rhinos or Apocalypses, move in with Iron Dragons behind and Centurion in front (or Centurion behind and Focus Tanks in front if Iraq). Then use Centurion to take out defenses from far away, along with any infantry and lone tanks, then the rest of your tanks can wipe out their base(s).

I rarely play as Epsilon, so no real strategy there. And if I'm Allied, I'm usually Great Britain.
