The TM-1 Missiles are weapons used by various armies in the Metal Slug series.
These anti-air rockets are extensively used by the Rebel Army. They're launched from a lot of places, such as Wells, out of nowhere, or from tanks. Contact with the missiles kills the player.
These can travel in both cardinal directions. Vertical missiles are used to block players from advancing forwards. Horizontal missiles attack the player but are safe to jump on top of them (except when riding the Slug Mobile).
There are two different models: the TM-1L is longer and slower, while the TM-1S is smaller and faster.
Rebel Army missiles have red highlights and have the "X" emblem on them. Amadeus Syndicate missiles have blue highlights and have the "A" emblem. Ptolemaic Army missiles have yellow highlights but without an emblem.
