OOC: Barak, a 110mm cannon would NEVER be able to tip over a tank, not even an APC like the rhino when not even an armoured train can. The only way a tank can tip over is if the driver takes it sideways over a way too high ledge (at least as high as the tank is wide). You tried to cover too much, the first post of a battle should be detection only. redo it and do it right or be ignored. (the odds look quite grim though, the armour, the posessed and the raptors is moving at around 30mph average, 12 predators with autocannon and heavy bolters, another 9 with lascannons in turret and sponsons, 30 rhinos, 10 dreadnaughts 9 land raiders, ~150 raptors and ~100 posessed, some of the possessed have wings, many have pre-heresy colours on their armours and yet some even has loyalist marine colours, they were captured and made unwilling demon hosts)
In low orbit:
The commander of the Scourge of truth reversed engines at full power, putting a stress on the hull that no fully man-made ship would sustain for long. Slowly, the shuddering hull moved backwards, decreasing the strike angle towards the puny loyalist warship.
"Master, upper bow shields at 50% but holding, servitors and dark mechanicus are working on the shield generators to increase output."
"Good"
"Master, alignment acchived."
"Launch bow torpedoes!, full salvo!"
The kilometer long missiles accelerated in their tubes as multiple warp rifts opened in front of the tubes with similiar rifts opening just inside the dreadnaughts mid-ship void shields.
"Time to impact 3... 2... 1... Impact!"
Three of the six warp-missiles launched went low and missed the Loyalist ship while still detonating against the far, inner, side of the dreadnaughts shield. The other three struck home, their magna-melta warheads impacting against the mid-ships battery decks.
