M18 smoke grenade

The M18 smoke grenade or AN/M18 was a colored smoke grenade introduced in late WW2 as a replacement for the M16 smoke grenade. During WW2, the M16 and M18 were visually identical, with yellow marking on a grey body. The M16 was later phased out, and the M18's body was updated to a white on green body.
The M18 smoke grenade is a burning-type smoke grenade that produces a cloud of colored smoke lasting 50-90 seconds with an average of 60 (the M16 burns for 2 and a half minutes instead). It is used primarily for signaling 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 HC smoke grenade), and is also used as a substitute for chemical weapons in infantry training.
The M16 smoke grenade was available in green, yellow, red, violet (sometimes mistakenly referred to as purple), blue, orange and black. The M18 eliminated the blue, orange and black variants. 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 the color was phased out until a new non-toxic violet was developed in the mid 2000s.
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 HC 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.
