An uncommon range of missiles used mainly against HMVs. Created by mistake, intended for fight in the void of space, they went into HMV fighting instead. Creating a powerful sonic and seismic discharge upon contact, they are very effective to tear apart armor and get HMVs off their feet, making them easier to destroy.
The downside of the missiles though is their relative price, as the components are difficult to maintain stable for long period of time without degrading. Also the fact that they are of different shapes than most missiles, they require specific pods to be launched, making customization a bit more expensive.
