===Vehicles and Special Equipment===

The sons of Tiran always boasted a large contingent of vehicles. Early in the Great Crusade, the Legion adapted bikes to their own use. As Tiran took command, he saw the abilities of the bikers, and how their use reflected his own personal tactics and strategies. Yet more was still needed. He brought in ever more armored vehicles. Most of which traded weaponry and heavy sponsons used in other Legions for increased speed. When interspersed among his troops, they acted as heavy fire support and mobile bunkers.

The base of Tiran's planning was always the basic Outrider Squad. Early in Tiran's redesign of his Legion, he discovered the initial design could not be produced in large enough numbers to supplement his entire force. Faced with this obstacle, he worked with his own Techmarines and members of the Mechanicum to find a working solution. The answer was within the Attack Bike design that had already been in use. Though heavier, it was also more robust, easier to maintain, and both cheaper and easier to mass produce. Initially dubbed the "Tiran-Pattern Bike," the name was dropped after the Heresy, where the Chapters as a whole adopted the design for the same reasons Tiran helped create it.

The Legion outfitted the bulk of their troops with the new Space Marine Bikes, and deployed them in squadrons much larger than most other Legions. As his military lines would move much faster than the standard line troops in other Legions, he replaced the bulk of his Heavy Support Squads with a combination of Attack Bikes, Jetbike Squadrons, and Land Speeders. Something which stands out among their deployments is the use of unusual Heavy Weapons on their Jetbikes and Attack Bikes. Multiple Missile Launchers have been seen on both chassis. Attack Bikes with Volkite Culverins and Jetbikes with Autocannons have been seen as well.

Supporting his line Bikers are the Predators, Sicarans, and Malcadors. They were often seen covering gaps in his own troops' movements and providing heavy fire to support the main effort. Against especially heavy fortifications, the usage of Breacher Squads delivered via Mastodon was not unheard of.

All of this would be considered impossible were it not for dedicated and resourceful Orbital, Sub-Orbital, and artillery support. Tiran always considered an artillery or orbital strike the linchpin in his major battles. This tactic worked excellently well during the Great Crusade, and Merrill's strike at them during the early days of the Heresy showed how important these strikes were to Tiran's overall strategy.
