The Slug Gunner is a super-rare unit in Metal Slug Attack. It is a very powerful tank unit, which can easily wipe out larger units with ease, especially if its skills are unlocked. It is a more effective tank unit than the Slug Armor, although the Slug Armor moves faster. The Slug Gunner can also easily take down much difficult targets like Ralf. Slug Gunner's unit parts are available via P.O.W. Rescue Shop or Elite 16-4 (Random).
