Berserkers

Berserkers were tough Orcs bred in Isengard.
== History ==
A new breed of Orc Berserkers plays a critical role in the final battle on Ravenhill. Bolg arrives at Gundabad and releases the legions, including the Berserkers.
The Berserkers run up the side of Ravenhill near The Lonely Mountain. The Berserkers are wiped out quite easily despite their strength.
They are portrayed as tall, bulky Orcs with pale skin and glowing eyes. 
They were larger, even more fearsome versions of the Uruk-hai, standing about six-and-a-half feet tall and weighing an estimated three hundred pounds. Before they were sent into battle, it is said that the bowl of their small, tight-fitting helmet was filled with the blood of their enemy, and then pushed onto their heads. The intoxicating smell awakened a blood-lust that drove them to a battle-frenzy and made them immune to pain. Berserkers had no regard for personal safety, wore no armor except their helmets, and were expected to fight to the death. Their sole object was to establish a bridgehead. One Berserker was given the task to set off the explosive mines planted by the Uruk-hai.
=== The Battle of Helm's Deep ===
For Helm's Deep they almost certainly would have been trained to climb onto the siege ladders as they were raised up against the Deeping Wall, then to buy enough time for their comrades, who were swarming up the ladders and in behind the Berserkers. It proved very difficult to get close enough to wound the Berserkers, so although they only numbered about thirty, they were able to inflict heavy losses on the defenders before they were finally all killed. Gimli himself accounted for three or more, hitting one in the chest and two in their nether regions.
The Uruk Beserker's main purpose at this battle was to:
* Scale the ladders the Uruk Sappers had brought from Isengard.
* Kill as many of the enemy as they possibly could when they reached the top of the ladders so there was room for the Uruk-hai swordsmen coming behind them.
* Ignite the blasting powder that Saruman had created for destroying the Deeping Wall, with their torches.
