1st Rule : Patience. Don't pop out and chase down that low health tank and get shot by the 3 other tanks waiting.

2nd Rule : Stay Alive. Being alive = more damage done to the enemy. Too much enemy coming? Relocate if possible.

3rd Rule : Read the wiki guide

feel the enemy ding ding ding on T29 head, 
what is the highest tier tank you have?
to join CW, u will need tier 10 tanks,

for clan war, you'll need to have multiple tier 10 available, be good at em, or be godly in 1 type of tank/td/arty. the hidden rule of cw is if you dont have a t10, gtfo you dont belong here. anyway, with the campaign rules now, the tier cap is t8 i think. lastly, of course be in a clan that actually do cw.

clan war = a chance to show off your e-pen. jokes aside, it's a series of battles where you fight to gain foothold on the game world map. clan that owns a land (province in this game) gain gold based on the province value, by the hour. this gold will then deposited into the clan treasury where it can be used for multiple stuff. the active clan with multiple high value provinces owned can easily give out premium tanks for its core members for example.

lol I used to care so much about stats and everything, keeping it high to seem pro. But now that the quality of players have gone down a crapload.....

I stopped caring. :/

8.10 update...

Germans are the ones with the highest hitpoints and armor. But slow, so it really balances out. Russians have the best camo value. Not sure about the others.

get KV1 or churchill 1, they trolling tier 5 like no body
