The Spinward Arm Crusade
9th Dokkalgard Dragoons
The Dokkalgard 9th Dragoons immediately preceded the 10th Dokkalgard Dragoons. They were destroyed by the forces of Chaos while fighting to defend an Imperial Shrine World. While the 9th and most of the other Guard units defending the planet were destroyed, they did manage to delay the Archenemy long enough that reinforcements were able to arrive and retake the planet.
Like all Dokkalgardian regiments, the 9th Dragoons specialized in Drop and Air-Mobile operations. However, the realities of the battlefield often meant they were employed as line troopers.
