Description: The Grenade No. 87 is a smoke rifle grenade. The complete grenade consists of a white phosphorus filled head, an adapter, fuze, and tail unit. The head is similar in construction to the Smoke Grenade No. 77 Mk I, differing only slightly in size and markings. An adapter which threads into the after section of the grenade head, is itself internally threaded to take the tail unit. The tail unit and fuze of this grenade are similar to those used in the Rifle Grenade No. 85.

Operation: Same as for the Grenade No. 85 except that explosion of the booster bursts the grenade case, spreading the white phosphorus, which ignites when exposed to air.
