The MH-6S Masknell is an enemy vehicle in the Metal Slug series.
The MH-6S Masknells are light utility helicopters used by the Rebel Army. The Masknells are fast, cheap, reliable, and can pepper the player with their 35mm gun pod. They usually work in packs and scatter all over to panic the players.
Occasionally, a squadron of five Masknells, headed by a red Regimental Masknell, will fly in a line and make strafing runs at the player. Destroying the red Masknell first will cause the entire helicopter column to crash into each other, netting huge points for the player.

|Regimental MH-6S: A red Masknell leading four other Masknells in a line. Eliminate the Regimental to destroy them all at once.|
|MH-6S ver P.M.: A variant of Masknell created by the Ptolemaic Army. It uses two guns on its sides instead of the 35mm gun pod on the front, which means it can cover more ground than the original. Found in Metal Slug 5.|
|MH-6S Ver.F: Also brought by the Future Rebels, it is better shielded and its gun pod fires blue projectiles instead of the usual orange. It is also painted blue. Found in Metal Slug 7/XX.|
|Golden MH-6S ver. P.M.: Gold-painted Ptolemaic Masknell that can stun and knockback enemies with their explosive bullets. It can also deploy itself at the frontlines. Found in Metal Slug Attack.|
- The Masknells are based on the American OH-6 Cayuse and MH-6 Little Bird helicopters.
- The Masknells are odd as there's multiple windows but no pilot is seen. Metal Slug 3D and Metal Slug Infinity has the pilot visible.
