This tank's key strong point is its speed. The tank has a top speed of 62km/h, which is easily achievable by the 180hp engine. It's also a very light tank, weighing in at only 7.2 tonnes (hence its classification as a light tank). This makes it a very hard-to-hit target while at speed.
The traverse of this tank is actually pretty decent. Even though it may seem a bit sluggish, the straight-line speed of the tank is usually enough to keep you from slowing down through corners. Time your turns correctly, and you can easily maneuver through the narrow streets of Himmelsdorf or the tight alleyways between the buildings of Port.
The main weak point of this tank is its armour. The best bits of armour on the tank are only 16mm thick, and the worst points are a measly 10mm thick. This thing can't seem to make anything that hits it bounce. Due to this, I would recommend against stopping your tank to fire while out in the open, as you will be killed very quickly if you do so.
The other strong point of this tank is its gun and turret. Both are quite good. Unlike some other tanks of its tier, the Tetrarch's turret isn't the weakest spot on the tank. The turret's armour (although there still isn't very much of it) seems to be good at keeping the gun and other modules from getting damaged, although I noticed I got hit in the ammo rack on occasion. The turret can turn at a decent traverse speed as well. The tier 4 (yes, you read right, tier 4!) 2-pounder gun itself is nice and accurate (with 75% crew, as tested), especially for its tier. Surprisingly, the gun is also decently accurate while moving. I can only imagine how good this thing's gun would be with 100% crew and a gun laying drive. Finally, the reload time of the gun is not very long (around 3 seconds), so lighting your enemies up with this tank is a breeze.
Overall Rating: 9/10
Honestly, this tank is among my top 3 favourite tanks in this game; the other two being the Somua S35 CA and ELC AMX. It's a very well-rounded tank overall, and suits my playstyle nicely. If the armour was any bit better, I'd actually consider this tank overpowered. I'd recommend playing this like a proper light tank: don't stop moving often, dart in and out of cover, and circle enemy tanks at close-range. You'll get quite a lot of kills if you play this tank right.
Hope this review is helpful to some of you guys, and as always, thanks for reading!
