Editing Warhammer 40,000/8th Edition Tactics/Death Guard (section)

===Grenade Storm===
Get a Biologis Putrifier, as many Plague Marines as you can, and use the Blight Bombardment stratagem for an impressive amount of shots, up to 20d6 if the squad is full size. Combine with Veterans of the Long War to get Mortal Wounds on a 5+, in case you want to take down heavy vehicles using only grenades. For extra fun, deep strike a Lord of Contagion with the Arch-Contaminator warlord trait. Since you can take Plague Marines in 7 man squads, one possible delivery method is a Rhino containing seven Plague Marines, a Biologis Putrifier, and two more characters, like a Foul Blightspawn for 2d6 extra grenades or a Tallyman for a follow-up charge. 
*The major weakness of this strategy is that the grenades are 6 inch range and everyone and their mother will see it coming. However, with the addition of the new '''Blight Bombardment''' stratagem, you can DOUBLE the range of grenades (to 12"), since they are Plague Weapons. Trying to line up the shot is very difficult without the aid of something like Warptime or a Dreadclaw. It feels like this would be a great backup strategy rather than a main battle plan.
**As a huge fan of grenades, I've spent a lot of time trying to make this work. I find it is most effective as a backup option for your shooty marines. Having a Biologus hanging out in the back might seem kinda expensive, until your opponent deep strikes a Dreadnought on top of you or their Hive Tyrant comes to play. Unload on them with your plasma guns and blight launchers, but rather than wasting all those bolter shots on a tough target, you can get a squad and a bunch of supporting characters to all chuck grenades. With an Arch-Contaminator nearby, and VotLW, you can decimate an expensive deep striker unit with minimal risk of return fire. I've dropped everything from Terminators to Mawlocs in a single shooting phase with a 7 man squad and 2-3 characters. 1d6 shots, 2 damage, and bonus mortal wounds add up fast.
# 'Alternate Take' put 3 units of 7 plagues marines geared for melee in a rhino with feel no pain and an arch-contaminator near, a foul blightspawn oand the biologus putrefier. This will give you a tanky enought blob that can advance agressively.
Since the damage of grenade combos and blade of putrification combos are insane, you just have a 20" threat space for you... And since your ennemy want to score points, it will need to take down these.
Given that this combos damage are so insane that you can make your point back with just one iterration, it become a possible battle plan.
This was played in tornaments in Europe for sub-leagues with some success before War of the spider and v9 ( with 5 units of 5 plague marines in rhino), and was buffed to the roof with this early v9... So brace yourself people, grenades are comming!
