Because infantry tanks did not need to be fast, they could carry heavy armour.
The official British Admiralty examination of the Grand Fleet's performance recognised two main problems: German armour-piercing shells were far more effective than the British ones, which often failed to penetrate heavy armour.
The impact of thousands of arrows, combined with the slog in heavy armour through the mud, the heat and difficulty breathing in plate armour with the visor down, and the crush of their numbers meant the French men-at-arms could "scarcely lift their weapons" when they finally engaged the English line.
An example of a battlegroup in the Reactive Force (e.g. the 1st Brigade) would be 2 companies of armoured infantry (e.g. from the 1st Battalion of the Mercian Regiment), one squadron of heavy armour (e.g. A Squadron of the Royal Tank Regiment), a company of engineers (e.g. B Company of the 22nd Engineer Regiment), a battery of artillery (e.g. D Battery of the 1st Regiment of the Royal Horse Artillery) and smaller attachments from medical, logistic and intelligence units.

Most of the French knights advanced on foot but, exhausted by walking across wet muddy terrain in heavy armour enduring a "terrifying hail of arrow shot", they were overwhelmed in the melee.
The Ottoman cavalry depended on high speed and mobility rather than heavy armour, using bows and short swords on fast Turkoman and Arabian horses (progenitors of the Thoroughbred racing horse), and often applied tactics similar to those of the Mongol Empire, such as pretending to retreat while surrounding the enemy forces inside a crescent-shaped formation and then making the real attack.
Ships of the line were superseded by ironclads, large steam powered ships with heavy gun armament and heavy armour, in the mid 19th century.

Unlike Space Marines or Necron, who boast heavy armour, high toughness and some form of wound-resistance;
Bomb disposal officers wear heavy armour and helmets with face visors and spine protection.
Throughout the day they were reinforced by more troops, heavy armour and T-34 tanks typically carried on flat-bed trucks.
Tank fired HEAT projectiles are slowly being replaced for the attack of heavy armour by so-called "kinetic energy" penetrators.
Developed in an era when HEAT warheads were thought to make conventional heavy armour of limited value, the Leopard focused on firepower in the form of the German-built version of the British L7 105-mm gun, and improved cross-country performance that was unmatched by other designs of the era.
As a weapon, the mace fell out of use with the disappearance of heavy armour.
The Kliment Voroshilov (KV) tanks is a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov which operated with the Red Army during World War II.

The KV's heavy armour proved highly resistant to Finnish anti-tank weapons, making it more difficult to stop.
This culminated in the KV-1 model 1942 (German designation KV-1C), which had very heavy armour, but lacked a corresponding improvement to the engine.
