A boarding harpoon functioned as a flexiglass based weapon, equipped with a hyper-thermal point, and it served the purpose of enabling boardings onto hostile vessels. This harpoon contained coma gas and was launched towards the targeted ship. In transit, the armored point of the weapon underwent a superheating process, allowing it to pierce the hull of the target. Upon breaching the ship's hull, the point would meld with it, preventing any possibility of extraction; furthermore, the release of the gas would induce unconsciousness in anyone exposed to it. The Myrkr strike team employed this typically prohibited weapon to subdue the Yuuzhan Vong combatants aboard a ship, which they then seized for transportation to Myrkr.
