- "Rogue Group, use your harpoons and tow cables. Go for the legs. It might be our only chance of stopping them."
- ―Luke Skywalker
The harpoon and tow cable, or power harpoon, was an improvised weapon system developed by Beryl Chiffonage and employed by the Rebel Alliance during the Battle of Hoth using tactics invented by Chiffonage and Luke Skywalker.
Operated by the gunner onboard a snowspeeder, the harpoon, tipped with a fusion disk, would be fired at the leg of an Imperial AT-AT walker. The pilot of the snowspeeder would then make several rotations around the walker to wrap the flexisteel cable around its legs. The walker would then become ensnared and fall over, effectively neutralized. Harpoons and tow cables were able to bring down a few AT-ATs at Hoth and were the Alliance's most effective method of dealing with the lethal Imperial walkers.
