The Battle of the Somme, or Somme Offensive, occurred between July 1 and November 18, 1916. The importance of air power and the first use of the tank are noted.

Only to a certain amount but it does Varies on what Tank it is, How much Armor it has got and where. All Tanks should usually take normal gun bullets but when it omes to tcank shells, it only takes a certain bullet depending on the tank to destroy another tank.

e.g. During WW2, The Soviets built the IS-1 Tank to defeat the German Panther and Tiger Tank, which the IS-1 had a 122mm, It was just capable to destroy the German Tiger Tank but required few direct blank shot hits due it's 120mm Armor. So as a response to the IS-1, The Germans brought out the King Tiger Tank which it had at best of 180MM of Armor. The King Tiger had 88mm Highly Explosive Gun.

So Tanks are only bullet proof if the ammo hitting the tank doesn't damage or most importantly penetrate the Tank Armor.

The USA was doing great during the war until the British tanks came along. From there we were in trouble. They bombed us and cut through our barbed wire and even destroyed our trenches. So we got flame throwers and realized they were able to destroy the tanks. So eventually we used tanks and flamethrowers and all that stuff and won the war.

Opinions will always vary, and are dependent upon the test conditions provided.

Over 10k Abrams have been built,and over 8k currently serve with the USMC and US Army.

Only 450 Challenger 2 tanks are in service with the British Army.

The M1 has the best combat record of any modern main battle tank,in the World today.Thats a true story.M1s have been lost,but M1s have made scrap yards out of other nations tanks.Sure,this was against inferior tanks,but it still got the job done,and a M1 has never been destroyed by another tank.Insurgants and road sides bombs have destroyed M1s,though.

It looked like a rounded oval box with caterpillar tracks on covering most of its side. With a 6 pounder sponson cannon on each side. This is the Mark IV one of the very first tanks in the world.

It's called a bore evacuator, and its function is to prevent gasses created from the firing of rounds from getting into the turret.

The IS-2 and IS-3 "Josef Stalin". They boasted a 122mm main gun, and remained the most powerful tanks in the world for almost 20 years after the end of the war.

Historically, tanks have ruled the battlefield - whenever they appear, they become the focus of all attention.

A tank has sufficient firepower to threaten practically anything on the battlefield (even helicopters, though not aircraft), and enough armor to protect them against all but the strongest weapons. A tank's main cannon generally has a lethal range of several kilometers. Most tanks have very good mobility as well, making them a mobile deadly threat. The combination of caterpillar tracks and a 1000+ HP engine can yield impressive towing capacity - most tanks can tow well over their own weight if properly equipped with the right towing gear.

However, they are not without weaknesses. Armor protection is not uniform; the top, rear, and bottom of the tank are vulnerable to a variety of lower-powered weapons that cannot harm the tank if used on the front or sides. Tanks are heavy, and thus cannot move across very soft ground, or cross many bridges, which restricts their mobility. Even the most fuel-efficient tank is a gas-guzzler, so they require vast amounts of fuel to move around. Most of these tactical weaknesses are magnified when fighting in constrained spaces, such a urban areas. Finally, they are expensive, at several million dollars each.

No tanks that i can think of ever used a key to start the main engine. Most starting procedures involved turning on the electronics then hitting the 2 master switches to start the engine.

Germany's first tanks were captured British tanks; they simply painted German emblems on them and sent them back against their former owners.

The M1A2 costs $6.21 million per, although there have since been upgrade programmes which have likely made the tank more expensive.

The only US tank in the army's arsenal is the M1 Abrams; and it's built by Chrysler. The Patton's in Vietnam were also Chryslers. The Vietnam Sheridan was built by General Motors. The M2 is the Bradley Fighting Vehicle, currently built by BAE Systems Land & Armaments (formerly of United Defense).
