* Reliability: Early tanks were notoriously unreliable, and could often break down after just a few hours of use. This was due to a number of factors, including the use of new and untested technologies, poor manufacturing techniques, and the harsh conditions of the Western Front.
* Speed: Early tanks were also very slow, with a top speed of only a few miles per hour. This made them easy targets for enemy artillery and machine guns.
* Armament: Early tanks were often armed with only a few machine guns, which were not very effective against enemy armor. This made them vulnerable to attacks from other tanks and armored vehicles.
* Visibility: Early tanks were also very visible, due to their large size and lack of camouflage. This made them easy targets for enemy snipers and artillery.
* Crew comfort: Early tanks were very uncomfortable for their crews, who were often cramped in small spaces with little ventilation. This could lead to fatigue and reduced effectiveness in combat.
Despite these problems, early tanks played an important role in World War 1. They helped to break the stalemate of trench warfare by providing a mobile firepower platform that could cross no man's land and attack enemy positions. Tanks also helped to protect infantry from enemy fire, and could be used to support cavalry charges.
As the war progressed, tanks improved dramatically in terms of reliability, speed, armament, visibility, and crew comfort. By the end of the war, tanks were a vital part of the Allied arsenal, and helped to lead to the Allied victory.
