 The two most common types of grenades are the DFS87 high explosive (HE), which has a fragmentation warhead with a casualty radius of 10-11 meters, and the DFJ87 high explosive dual purpose (HEDP), which has a shaped charge warhead that can penetrate 80 mm of rolled homogeneous armor (RHA) which striking flat or 35 mm of RHA at a 60° angle with a secondary 5-meter fragmentation casualty radius; though both these rounds have better anti-personnel and armor piercing effects individually than U.S. 40 mm HEDP, their specialization makes them less suited for defeating a different target set, so ammunition type would have to be changed to effectively engage a different target type.Initial production of both models featured a fragmentation liner consisting of small steel balls suspended in a polymer matrix, but later the HE projectile used a pre-fragmented wire coil jacket and the HEDP projectile used a steel upper casing to produce fragments, both for cost savings.They have an inertia-armed fuze in the nose permitting a safe arming distance of 12–30 meters from the muzzle.
