Description
The Grenade No. 85 is an antitank, cavity charge grenade patterned after the US Army M9A1 and similar in construction. The Mk I is fitted with Fuze No. 430 Mk I, which will function satisfactorily on impact up to 45° from the normal. There is no safety pin to withdraw, and the fuze does not arm until the grenade is fired. The Grenade Mk II has the same head but is fitted with Fuze No. 431 Mk I, which differs from the Fuze No. 430 in that it has a longer booster, and is easier to assemble and inspect.
The Grenade No. 85 Mk III is similar to the Mk I except for the fact that the lower body is wire wrapped to increase fragmentation, allowing a dual employment as either an antitank or anti-personnel grenade. The tail tube and fuze are made of a light alloy in the Grenade Mk III. This change of material gives the fuze the designation No. 431 Mk I/I.
