M18 smoke grenade
The M18 smoke grenade or AN/M18 was introduced in the early 1950s as a replacement for the WW2 M16 smoke grenade. It is a burning-type smoke grenade that produces a cloud of colored smoke (green, yellow, red or violet, dispensing with the blue, orange and black versions the M16 had) lasting 50-90 seconds with an average of 60, and is used primarily for signalling and as a marker for landing zones or air or artillery strikes, though it can also be used to produce obscurant smoke (less efficiently than the dedicated AN/M8 smoke grenade), and is also used as a substitute for chemical weapons in infantry training.
The smoke formula is the same type used in the M713, M715 and M716 40mm grenade rounds, being mostly a reaction of potassium chlorate with a fuel to disperse smoke loaded with a chemical dye. At some point in the late 80s or early 90s the smoke formula was changed to use sugar instead of sulfur as a fuel for safety, along with changing the composition of the dyes. It was quickly found that the new violet formulation was extremely toxic, and so newer-production M18s are only manufactured in green, yellow and red.
The M18 smoke grenade appears in the following films and video games used by the following actors:
NOTE: The M18 smoke grenade only produces colored smoke. If a smoke grenade releases white or grey smoke, it would in real life be an AN/M8 smoke grenade or M83 smoke grenade, though since in media the smoke is seldom the product of a live grenade being used (as military smoke is toxic) this is not necessarily proof of ID.
