Why were Tiger tanks best suited to defensive combat?

The Tiger tank (Pz. VI) was best suited for defensive combat because its design prioritized firepower and survivability at the expense of speed, agility, and mechanical reliability.1

Several key factors made it effective in a defensive role:

• Superior Firepower: It was equipped with a long-barreled, high-velocity 88-mm gun capable of penetrating the most heavily armored enemy tanks at extremely long ranges.1
• Heavy Protection: With frontal armor up to 100 mm thick, the Tiger was proof against almost any antitank gun of the era.1
• Mobility Limitations: The tank's significant weight—ranging from 55 to 70 tons—severely compromised its speed and cross-country mobility. It was also prone to mechanical breakdowns and difficult to maintain, making it ill-suited for the rapid maneuvers required in offensive operations.1

Because speed and agility were not decisive factors in defensive positions, the Tiger could effectively leverage its long-range gun and thick armor to destroy enemy forces before they could close the distance to exploit the tank's vulnerabilities, such as its weaker side and rear armor.1
