3 Dreadnaughts with Assault Cannons, Heavy Flamers, and extra armor
3 Predator Destructors with HB Sponsons
6 Multi-Melta Land Speeders (3 Squadrons of 2)
2 x 9 Marines Vet Serg, Power Fist, Frag Grenades with Rhino and extra armor
2 x Librarian-Epistolary with Bolt Pistol, Terminator Honors, Veil of Time, FOTA- Attached to Rhino Squads
My strategy for this list would be to deploy the Predators, in the center if I have LOS or can move to get it, allowing me a bit of leeway in how I deploy the rest of my force, I will be using my Rhino Marines to rush up to engage his anti-tank units on one side, while my own Speeders rush from the other side to shatter his own vehicles. . . the Dreadnaughts will be remaining as close to the Rhino Marines as possible, or following in the wake of the predators depending on his force. . .
In escalation, I don't really have a solid plan yet because of the randomness of my reserve rolls. . .
