Horse Jade Falcon
Horse was a freeborn Clan Jade Falcon MechWarrior and Star Commander of the elite Jade Falcon cluster Falcon Guards. He was later reassigned to create and lead a trinary of elite freeborn warriors. In this process he was awarded the rank of Star Captain. This unit receives its orders directly from Khan Marthe Pryde.
He is most notable for his constant service to the Jade Falcon leadership and for his role in the career of Aidan Pryde; arguably Clan Jade Falcon's most legendary MechWarrior.
Horse's real name is Tyle (after his father), but he dropped it, when he received the nickname "Horse" because of his bristling breath.
Horse is honored by several lines in the Remembrance (apparently relating to his role on Tukayyid). Maybe he is also mentioned in the lines referring to the historic battle on Waldorff against the Steel Vipers, where freeborn Jade Falcon forces held out against the elite of the Steel Viper touman, eventually defeating it's Khan.
Horse, being a freeborn, was discriminated against by the trueborns that dominated the Clan leadership. Regardless of this, he attempted to join a freeborn training sibko, and was successful in his efforts. During his training, he met Aidan Pryde for the first time on the field of "battle", in the course of which he almost killed Aidan with a knife. Horse, however, lost the battle and went back to training.
Horse was successful in training, having remained in the sibko to a point where only four members were left. However, the normal arrangement was complicated by the entrance of a freeborn warrior called "Jorge". Jorge was actually Aidan in disguise, having been given a second chance by his sibko commander Ter Roshak at a Trial of Position. In marked contrast to their first meeting, the two of them quickly came up with a strategy for passing their Trials. They both succeeded, and were made full MechWarriors of Clan Jade Falcon.
Horse and "Jorge", after various dull assignments, wound up on the planet of Glory, a desolate planet with strange topography. On-planet, however, the Jade Falcon base was attacked by Clan Wolf troops, and nearly fell due to sheer numbers. Horse and Aidan, however, served in the defense, and came up with the winning strategy that left the Wolves in a shambles. Aidan used his sudden good-standing to declare himself a trueborn, and therefore eligible for a Bloodname Trial for the name of "Pryde". An investigation soon mounted, however, and Horse got subpoenaed for testimony on the planet of Ironhold. Once there, Aidan, his commanding officer Joanna, and Ter Roshak fought the verdict, and were ultimately successful. Aidan won his trial for the Pryde Bloodname.
After the failed campaign on Coventry in 3058, Horse was promoted Star Captain and recieved orders from Khan Marthe Pryde to create a 'Mech-Trinary with elite freeborn warriors. Khan Marthe Pryde said, this would be a special unit, recieving direct orders from her. The warriors should be freeborn, as trueborns would protest in some situations, that this or that action would mean a loss of honor. Freeborns are much more pragmatic.
The first mission (in 3059) of Khan's Irregulars was to inspect the Jade Falcon installation on Huntress, the Clan Smoke Jaguar homeworld. It was a very small installation, where dual-cockpit LAMs were being developed. Though Jade Falcon ships have gained the right to land in that installation, Horse's dropship was shot down. He and his warriors were taken prisoner and their mechs were seized. Galaxy Commander Russou Howell was bored and used Horse to provoke and shame his own substandard warriors. He tried to convert Horse into a Smoke Jaguar, but Horse resisted. The solahma Sentania Buhallin freed Horse in a trial, using the two stolen LAMs. Russou bid himself and Horse to fight against the Jade Falcons. That meant, that Horse had to fight with all his skills in order to remain a prisoner, or he would lose his honor. Horse lost honorably and was free. Horse's fellow warriors and mechs were freed in a prisonbreak. Horse finally issued a report to the Khan, recommending closing the installation and canceling it's LAM-program.
In 3060 the Steel Vipers tried to annoy the Jade Falcons by claiming that the freeborn Jade Falcon warriors were essentially weakening their touman. Khan Perigard Zalman taunted Marthe Pryde, until she lost her temper and challenged him to a trial. Kael Pershaw reminded both Khans, that Khans were no longer allowed to fight directly against each other. Both had to choose a champion, who would fight for them. Perigard Zalman chose Star Colonel Ivan Sinclair. Marthe Pryde made a choice that would make a Steel Viper loss even more shaming. She chose the best freeborn warrior she knew: Horse. Horse won a narrow victory.
Steel Viper-Jade Falcon War
Clan Steel Viper had secretly shipped reinforcements to it's occupation-zone in the Inner Sphere und used them to conquer 13 worlds of the Jade Falcon occupation zone in early 3061. Khan Marthe Pryde arrived troops in mid-3061, among them Horse and his trinary.
Slowly, world by world, the Steel Vipers were defeated. The final battle took place on Waldorff, where several elite clusters of both sides fought against each other. Through a clever maneuver by the Steel Vipers, the Falcon Guards and Horse's unit were first separated from the rest of the Jade Falcon forces and then split into smaller elements. Horse's trinary and elements of the Falcon Guards were ambushed by the Triash Keshik. Among them was Ivan Sinclair, who challenged Horse to a duel one on one, separate from the rest of the battle. They fought and finally both their mechs ended up disabled. They left them and went on with a fistfight which also ended with a draw.
In 3069, Joanna and Horse apparently saw action on Marshall in the Kerensky Cluster, though not in battlemechs. The exact opponents they fought and even the circumstances are unknown, however it is common in clan tradition to use aged warriors as cannon fodder in battle, using them as unarmored infantry with little chance to survive. Despite this, there is no actual mention of Horse's death. 
- In the German translation of Falcon Rising and Freebirth novels, Horse's command created by Marthe Pryde, Khan's Irregulars was given different name. The novels referred to them as The Khan's Partisans.
