All vehicles have armor, which protects them from enemy fire. Some vehicles are heavily armored and others are less shellproof, yet armoring on most vehicles follows a common principle: the front armor is usually thicker, while the sides and rear are more vulnerable. Hull armor thickness is measured in millimeters. In vehicle characteristics, these values are displayed as front/side/rear armor. If a vehicle has 75/45/45 mm hull armor, a shell with a 60 mm standard penetration will pierce its sides and rear (assuming a direct hit), but will not penetrate the front.
Apart from side and rear armor, most vehicles have common weak spots: the lower glacis plate, the commander's cupola, and the top surface of the turret.
A crucial factor in determining penetration is the angle at which the shell hits the target's armor. The ideal angle is perpendicular to the armor plate—in this case the shell has to pass through the least possible amount of armor plate in order to penetrate it. The perpendicular shell trajectory—the shell striking the armor plate exactly "square on"—is referred to as the normal.
The deviation from the normal is the so-called impact angle which determines the effective armor thickness. It is the actual armor thickness the shell must plow through in order to penetrate and deal damage. The greater the impact angle, the greater the effective thickness of the armor.
Keep in mind though, shells do not always penetrate vehicle armor. They can also bounce off the surface—this is called a ricochet. A ricochet can occur with Armor-Piercing (AP) and Armor-Piercing Composite Rigid (APCR) shells if the angle at the point of impact is greater than 70 degrees. High-Explosive Anti-Tank (HEAT) shells can ricochet at angles greater than 85 degrees (see Ammunition). Only High-Explosive (HE) shells never ricochet: if they don't penetrate the armor, they explode on its surface.
Remember these core rules of penetration and ricochet when firing at enemy vehicles. Always try to reduce your shells' angle of impact to maximize their chance of penetration. Moreover, you can make the most of your own armor and increase your chance of survival. Don't face the incoming fire directly: keeping your armor offset slightly will increase the impact angle of incoming shots, as well as your effective armor thickness.
Here are some useful techniques that you can use in combat to deal more damage.
To hit a moving target, aim and shoot at the front or ahead of the enemy vehicle. The greater the distance and the greater the speed of the enemy vehicle, the farther ahead you should aim.
Activate Auto-Aim when you are focused on maneuvers and cannot aim your gun manually. It allows you to automatically lock on an enemy vehicle, aiming at its middle.
Your enemy is so tough that your shells do little or no damage? Switch to destroying modules—tracks, in particular. This tactic is especially effective against heavily armored vehicles of higher tier. Knocking out tracks can keep the opponent immobilized so that your more powerful allies can focus and destroy the enemy. In the end, you will be rewarded for the damage caused with your assistance.
Always take advantage of terrain on the battlefield! Hide behind boulders, hills, and buildings to protect yourself from enemy fire or while you wait for your gun to reload. To stay safe from SPG fire, take cover behind large rocks, buildings, and other tall, massive objects.
In addition to staying safe, you can use terrain to gain a position where you can fire effectively without taking damage yourself. The tank in the picture is positioned behind a rise, so that opponents can see only its heavily armored turret. Meanwhile, the more vulnerable hull is hidden and safe.
Dangers on the Maps
Be cautious in your maneuvers: terrain can be dangerous! Don't plunge off steep cliffs! If you're lucky, you'll just take damage to your vehicle, modules, and crew, but most likely, your vehicle will be destroyed.
Lakes, bays, deep rivers and canals—any deep water can be hazardous. Be careful while driving across bridges or finding shallow places to cross deep water. If your vehicle—specifically, the engine compartment—goes under water, you have only 10 seconds to save it from drowning.
Upon performing extreme maneuvers, your vehicle may fall onto its side or even overturn – light and fast vehicles have this issue more often. A vehicle laying on its side is not only immobilized, but also almost defenseless: its view range, accuracy, and firing speed are significantly impaired. An overturned vehicle cannot fire at all and self-destructs after 30 seconds.
Your teammates can push your vehicle carefully to bring it back onto its tracks, but this does not always work.
Vehicle's View Range
It's hard to fight an enemy you can't see. The earlier you spot enemy vehicles, the more advantage you have in battle. That's why spotting is one of the core elements of World of Tanks game mechanics.
View Range is the maximum distance at which your vehicle can spot opponents. This parameter is defined by vehicle characteristics, modified by crew perks and skills.
To have a complete picture of your vehicle's spotting and view range capability, you can use special circles on the minimap that depict proximity spotting range, view range, maximum spotting range and vehicle draw distance.
- Proximity Spotting Circle. A 50 m radius in which the vehicle is automatically spotted despite obstacles and concealment.
- View Range Circle. Shows the View Range value of your vehicle, adjusted in accordance with the skills and perks of your crew and equipment mounted on your vehicle.
- Maximum Spotting Range. The maximum spotting range of all vehicles cannot exceed 445 meters. Even if your View Range exceeds this value, you won't be able to spot an enemy on your own beyond this distance; however, it will be easier for you to detect concealed vehicles within this range.
- Draw Circle. Shows the maximum draw range within which other players' vehicles can be seen on your battle screen. This value is always 565 meters.
Another essential component in spotting and keeping track of the enemy is Signal Range. Your vehicle's Signal Range is the maximum distance at which you can exchange information with your allies about other vehicles' position. Signal Range values are defined by radio characteristics, modified by crew perks and skills.
If your ally spots an enemy and is within range to share this information with you, the icon of the spotted vehicle will appear on your minimap, even if the vehicle is beyond your Draw Range and cannot be seen directly. So you'd be wise to get the best radio available!
Staying out of the enemy's sight will help you survive the battle and deal more damage. Learn to conceal your vehicle!
Thick bushes and fallen trees can conceal your vehicle. Remember, your entire vehicle must be blocked by the foliage, otherwise you will not be hidden. The exception to this rule is your gun: if your gun extends beyond the bush, it will not ruin your concealment.
If you are within 15 meters of the bush, you will be able to see other vehicles through it. You'll be not only out of sight, but also in position for an ambush.
Concealment drops dramatically when you fire a gun. Shooting also negatively affects the flora within a 15-meter radius, making it transparent. At the same time, gun and turret traverse do not affect the concealment of any stationary vehicle.
You can improve your vehicle's view range and reduce it's visibility by using equipment, consumables, special crew perks and skills, camouflage, and Directives.

World of Tanks features five vehicle types, and each of them requires certain tactics on the battlefield.
Light Tanks. Light tanks are the eyes and ears of the team. They are the fastest tanks and have great View Range, but usually thin armor and fairly poor firepower.
Medium Tanks. Multi-purpose combat vehicles. They combine mobility, firepower, and relatively good armor, so they are useful both in frontline combat and in a support role from mid-range. However, Medium tanks should not fight alone: a solo Medium tank is typically easy prey, while several in a pack can quickly dismantle opponents.
Heavy Tanks. Heavily armored vehicles with powerful guns. Their main role is to push a flank or meet an enemy push, dealing massive damage and blocking enemy fire with their thick armor. This type of vehicles is relatively slow and usually has a low fire rate. Also note that heavy tanks are usually the favorite targets of enemy SPGs.
Tank Destroyers. These are snipers with accurate and powerful guns. Generally compact and easy to hide, they seek to fire at long distances while staying completely unseen. Tank destroyers are often turretless, poorly armored, and slow, so they are vulnerable in close combat.
Self-Propelled Guns. SPGs, also known as artillery, provide long-range firepower for the team. They are able to hit targets almost anywhere on the map, and their HE shells deal splash damage, sometimes to several vehicles at a time. Shells of 150 mm caliber and greater also have a stun effect, which temporarily weakens all vehicle characteristics of the target. SPGs are slow, and their armor is extremely weak.
