147. Colored Smoke Grenade M18, designated as above, is similar to Colored Smoke Hand Grenade M16 in paragraph 146, except that the burning time of grenade M18 is reduced to one minute. It thus produces a larger and denser cloud of smoke than the Grenade M16. Grenade M18 is designed to supersede Grenade M16 eventually. Instructions for use are the same as those for White Smoke Hand Grenade (HC) AN-M8, as described in para-graphs 141 to 145, inclusive.
