The shockwave pod is another variant of the standard NARC pod. It replaces the magnets and the homing beacon with a huge explosive charge that is detonated by a couple of different fuzes. A proximity fuze can detonate the charge when it's up to ten meters over ground or away from an obstacle, while a time fuze detonates it after the pod traveled a specific distance.
Designed to clear minefields at first, the shockwave pod also proved very useful against conventional infantry and vehicles, battle armor and ProtoMechs, but relatively weak against BattleMechs, since they have a reinforced structure and lots of curved armor plating that protects them from the blast.
