Do you guys have tips for Cold War?

Basic tips for CW beginners:
Always act like you are spotted, even though 6th sense has not activated. The mode has True Vision, which means your tank is always visible to the reds. Take advantage of hard cover, learn the normal sniping spots and their sight lines so you can avoid them while moving.
It is rarely ever a good idea to take on enemy reds alone. Try to stay in view of your own teammates.
If you are in the beginner tanks,follow behind your team's stronger tanks. Assist them when they engage an enemy.
You will have a difficult time penning anything from the front, so practice flanking and getting to the side or rear of the enemy tank.

In Era 1 it is imperative you check the team make up before each match. If you see one or more Obj 268 on the enemy team, pay special attention. You need to find out where this tank is playing and avoid being seen by it. This TD can one and two shot the beginner tanks.

If you peek over a ridge, don't stay there too long. Too many times I have taken out people who weren't detected so stayed in my view, despite being hit by shells. If you take one hit, drop back down and move to another spot before poking up again.

Most tanks can take a few hits before being destroyed. Plan escape routes and use them if you get hit.
The quickest way for a tank to get destroyed is to be shot by multiple tanks at once. Pay attention to the map to see where groups of enemies are.

Some basic advice. There is a bit to learn in CW. It plays differently from WWII. Paying attention pays alot of dividends. The good thing is you don't have to worry about arty dropping on you as there is none in CW.

Tinypic itself was an image-hosting site much like how Imgur is, with the exception that tinypic itself has shut down a while ago.

While you can make direct uploads to here for your avatars and such, another option is to use a direct web link for the image in question. Sometimes that link ends up leading to a website that has shut down, hence, the tinypic errors.

Another cold war tip for you guys to get back on topic...

By and large, sod buying the radios! They're mostly a waste of your silver due to the nature of true vision, as any tank that is spotted is visible from another map (figuratively speaking).

And modules, even in era 1? Not cheap. You'll find the usual blockades to progress in the CW tech tree to be Silver, not XP, so it's imperative you avoid radios as much as you can.

Really fond of Warships, just wish allies were a bit better (like tanks), it's frustrating to be getting zero support because your teams BBs are in the dar corner. 

Just thought of another tip about CW, R35T. Large smokescreen is amazing. I guess you probably are familiar with it from ships, but in case you aren’t using it yet on tanks… It’s fun to use and worth the silver cost for the large one because it gives a passive camo boost at all times. You can use it the normal way, just to make a cloud to escape, but you can also use it to make someone think you’re about to peek on one side and then shoot them from the other side of your cover. You can throw it in front of you while running away and then disappear into it and circle around. You can use it to prep an alley before crossing the road. You can throw it on top of an enemy so several friendlies can surround them. Just be aware the bots see right through it, it only works on players.
