Grayson Death Carlyle (born 21 May 3004 – died 22 May 3065; aged 61 years) was the commander of the famous mercenary unit Gray Death Legion. Known for his innovative battlefield tactics, especially the use of anti-BattleMech infantry, Carlyle is widely acknowledged as the father of 31st century warfare.
Grayson Death Carlyle is a tall and slender man with blond hair and gray eyes.
Grayson Carlyle was born on Calaeras as the son of Captain Durant Carlyle, the Commanding Officer of Carlyle's Commandos, a House Steiner BattleMech lance. Therefore throughout his whole youth he was groomed to take his father's position someday and at the age of ten he formally joined the unit as a MechWarrior apprentice. Shortly after the death of his mother the Commandos were sent on garrison duty to Trell I in 3019. Grayson's life would change abruptly in 3024 when a mysterious bandit force attacked the Commandos, shattered them and drove the survivors off planet. As the only member of his unit left on the planet Grayson's only thought was to take revenge for his father's treacherous death by the bandit leader's Marauder. His astonishing success against several light BattleMechs while he was on foot deeply impressed the planetary militia and the government, which thereafter offered him a job to set up a 'Mech force as defense against the bandits. Carlyle started with the recruitment of an enemy MechWarrior, who was taken prisoner during the attack, called Lori Kalmar, for his new Trellwan Lancers. Under Grayson's skilled command the Lancers managed to achieve additional victories and finally uncover the invaders' identity as a special force of Duke Hassid Ricol of the Draconis Combine. Ricol's intention was to arrive with a second force and "rescue" Trell I's population from the bandits to secure a safe haven for further incursions into the Lyran Commonwealth. This discovery instilled in Grayson a great sense of hate for the Combine. At first the situation got even worse when Ricol arrived with a company of heavy BattleMechs and the Trell government was overthrown by Combine collaborators. But finally the Lancers managed to inform the Commonwealth by hijacking a JumpShip and after Ricol was unable to destroy Carlyle's forces in a final battle, the Duke was forced to withdraw his troops off planet. Grayson on the other hand had to learn that his desire for revenge could be dangerous, especially for his relationship with Lori, when he was fighting against his father's murderers instead of rushing to her rescue. Though he was not able to kill Ricol or the pilot of the Marauder, Grayson's desire was stilled for the moment and he left the world with the remains of the Lancers, that swore allegiance to him to create a new mercenary unit: The Gray Death Legion.
As Commander of the Gray Death Legion
After landing on their new home, they were attacked by the Free Skye Militia secretly supported by Ryan Steiner, however Victor Steiner-Davion secretly hired the Northwind Highlanders to assist the Gray Death Legion in the successful defense of the planet. 
Grayson received an injury during an attempted assassination that prevented him from piloting a 'Mech any longer. Grayson's wife provided him command of a group of power-armored soldiers in the Gray Death Legion called Carlyle's Commandos, the name of his father's command.
Death and Legacy
Carlyle died in 3065 of cancer. His wife Lori inherited his 'Mech and position as CO of the unit. Grayson was the founder, heart, and soul of the Legion, and his beloved Gray Death Legion would not outlive Carlyle for long (the unit would be destroyed later during the same year). His revolutionary battlefield tactics were adopted by military units throughout the Inner Sphere and would be taught at academies for decades to come.
Carlyle started with Lori Kalmar's Locust on Trell I until he managed to recapture the Shadow Hawk of his father's unit. On Verthandi he was able to purloin a Combine MAD-3R Marauder. Grayson piloted this 'Mech during most of his career, before it was ravaged in combat against the Clans on Sudeten in 3050 and he was forced to abandon it. Grayson replaced the Marauder with a much more advanced VTR-9K Victor.
