A Grapple Rod is common piece of disposable gear used by infantry trained in anti-BattleMech tactics among other uses. It consists of a meter-long metal shaft containing a powerfully adhesive dart attached to twenty meters of cable and a powered winch. When activated by the trigger near the middle of the shaft, a small explosive charge propels the dart forward up to the entire length of the cable. If successful in adhering to the desired target, the user then puts his foot into a stirrup attached to the end of the rod and activates the winch, propelling themselves upwards at great speed. While very adhesive, the dart will not adhere to certain surfaces, such as melting ice, and the cable can only support 150 kilograms of weight.
