Astartes anti-plant grenade
Astartes Anti-Plant Grenades are a more lethal version of the common anti-plant munitions used elsewhere in the Imperium. These grenades are popular amongst the Deathwatch Scouts of the Jericho Reach.
Astartes anti-plant grenades releases a vicious cocktail of toxins, viral agents, defoliants, and anti-fungal agents on detonation that reduce even the heartiest flora to a foul-smelling muck in minutes. They are typically used to deny cover and to clear landing zones and fortification sites.
