You sure about that? It only states "This unit can charge on the same turn they disembark from the Karybdis Assault Claw." To my knowledge you can keep the unit inside the droppod when it comes in - But they still arrive from reserve.
If they were to come in and assault the same turn, then I believe it should have been worded "This unit can charge on the same turn they arrive from deepstrike".
Maybe I'm reading too much into it - But it seems like one of those cases where it can easily be argued that they still cannot charge when they come in from reserve.
Quote from BRB for special rules Deep Strike
In the Movement phase during which they arrive, Deep Striking units may not move any further, other than to disembark from a Deep Striking Transport vehicle if they are in one.
Otherwise it would be stupid to also have the rule there anyway as once the Kharybdis has deep striked anyway it is counted as a Flyer with Hover and is an Assault Vehicle anyway, so they can always assault on the turn they disembark in any other turn.
Also just noticed something (so amended previous post) Strangely as well if you missed all those Vehicles or Buildings you could drop off the Berserkers, go Flat Out in your shooting phase to move 18" and fly your way off the board and deepstrike again in the following turn and try again
Though the troops loaded in this time you wanted would not be able to assault on coming out.
those are expensive formations, are they for apocalypse or something?
It says "Although these Formation represent those that fought in the bloody siege of Angelus Prime, this conflict is far from the only timer that they have seen battle. As a result, you should feel free to use these Formations in any of your games of Warhammer 40,000"
But yeah the Ultramarine formations are a little expensive as they are 100 marines (60 tact, 20 assault, 20 devs, 2 dreads and a couple of chars, OR 100 veterans / termys + 3 ven dreads and a couple of chars) so about 1500-4000pts I guess. The Chaos ones are still expensive as said with the Hellforged Hunting Pack as a base of 1700 I think and upper limit is 2300 I think. An'grath and his 8 Blood Thirsters would be 2888 min and 3288 max.
Though the Khornes Fist is just the 650pts + any optionals you want to buy like chainaxes, melta bombs and stuff. But also remember they could come in on DropPod assault so 50% of your droppods rounding up can come in on turn 1. So if you take 1 of these formations you could guarantee they come in on your first turn and could also charge!
The Blooded Horde is also a not massively expensive 1160pts, especially as that is 64 bloodletters, 6 juggernauts and 2 skull cannons. Add on a Slaughtercult (Herald, 2X 8 Bloodletter, 5 Possessed) and Gorepack (2X 3 Bikers and 5 Hounds) for a Bloodhost army for about 597pts min I think, and that is 1757pts, so a bit of room for upgrades and additional bodies if you want.
