The Krios Battle Tank is the mainstay of the armoured cohorts, making use of technology that was strange and ancient even at the time of the Horus Heresy to create a phenomenal all-rounder with impressive speed in one package. The usual armament is a lightning cannon that can evaporate entire squads in a single well-placed blast, and it can be replaced with a short-ranged irradiation blaster for extra lethality.
Alternatively, you can build this kit as a deadly Krios Venator a dedicated tank-killer armed with a powerful but relatively short-ranged pulsar-fusil.
