#### Units of Note

*10th Ballistic Artillery Regiment:* Known by their motto, "Big Guns On The Way", the 10th are a "mongrel regiment" of veterans of a variety of different Kronus campaigns. They deploy 48 Basilisk self-propelled howitzers and are typically deployed as a unit, serving as auxiliaries to divisions requiring fast-moving artillery support. They distinguished themselves in the early days of the assault on Dalarus during the Kronus Campaign, where they provided close-range direct fire support for a Stormtrooper brigade, preventing their being overwhelmed by Ork Speed Freaks.*81st Assault Launcher Regiment*: Three rocket artillery battalions, each equipped with two batteries of four Praetor Armoured Assault Launchers each (24 launchers total in regiment) and two batteries of support, plus a HQ battalion that coordinates recon, target designation, and resupply. The heavy and flexible Praetors are deployed to smash key defences at long range, saturate incoming enemy movements, and provide high-impact mobile air defence screens. The regimental support units include Hydras to afford the valuable and slow-moving Praetor launchers additional protection from airstrikes, and Salamander scout tanks to serve as outriders when on the move and forward observers when the launchers are in firing position.
