I went to the link posted that enables us to see our progress in the war, but when I entered my nickname to see my progress it says "This tanker is not participating in the «War of Super Powers» yet" ,even though i bought a paint.

There is only 1 kit for firebird m3; promitheus kit. So if I am going to buy a firebird m3 kit I have only 1 choice. So I think we need at least 1 more product kit with firebird m3.

I found that collecting crystals much more effective. I bought many m1 turrets and hulls including thunder,twins,rail,rico,smoky,fire,isida etc and wasp,hornet,viking,titan,mammy. I liked thunder,twins and viking combos very much. So i upgraded vikings armor fully before that micro upgrades update in 2015, so i got that m2 free. Later I realized that twins m1 is still good at even ranks like captain. So i just bought annihilator kit and saved for bulldozer kit. I could buy it in the recent tankers day. At that time i had about 390k crystals collected from daily missions and ended up having about 240k remaining after the purchase. So I'm telling u that just 1 or 2 m2 combos are enough for that ranks and it will help u a lot in the future.
