UK
Armored fighting vehicles produced and fielded by Great Britain and the British Commonwealth, focused primarily on Britannic development. British tanks normally will be found with one or two great strengths and one or two great weaknesses at the same time. Best suited as high speed spotter tanks, low speed heavy breakthrough tanks, medium to short range anti-tank fire, or all around equally maneuverable, high-speed, and versatile armor capabilities.
Going into detail, the British Mediums start off fairly fun to use. Going to the Cruiser series, you see the first use of one shot burst guns. This teaches you to take your time and aim, as the reload is not the handiest at its tier. Hitting up to the Cromwell, you see a bunch of capable flankers. Low alpha guns, weak mediocre guns, but excellent mobility allows them to sneak around the enemy, not to also mention the good camouflage it has. Once you hit the Comet, you start to hit the turning point of the British Mediums. play style turns from a fast scout/flanker to a second-line brawler. The Centurion 1 gets a proper mantlet, comparable to the Caernarvon. Mobility goes down, and so does profitability. Topping off with the FV4202, the British line does go through a number of changes. Whether you like to be a low-tier killer or a high-tier brawler, just make sure you have a profitable credit source, and you are sure to have great memories with this line of tanks.
The British Heavies are a different story however. You start off with the Vickers, probably one of the most hated tanks of the low tiers. Tier 1, 2, and 3 are a torturous experience as you have terrible armor, mobility, and a humongous silhouette. The only compensation you do get is a fair gun, but sometimes it is under performing in some matches. The Matilda for many, is a breath of fresh air. You finally see...
