182:. This allowed the thrower to use a grenade even when there was little in the way of defensive cover. In contrast, the much greater destructive radius of the Mills bomb than its throwing range forced users to choose their throwing point carefully, in order to ensure that they would not be wounded by the shrapnel explosion of their own grenade.
243:. Normally, impact-detonated munitions must hit the target with a particular point of impact (i.e. perpendicular to the fuze mechanism) in order to detonate. In contrast, no matter which way the No. 69 grenade hit the target (e.g. landing on its base, or sideways or upside down) it would still explode.

Using the No. 69 bomb was very simple: the screw-off cap was removed and discarded, and the grenade was then thrown. When the grenade was thrown, a linen tape with a curved lead weight on the end automatically unwrapped in flight, freeing a ball-bearing inside the fuze. In this manner the "all ways"

The fuze was worked by the user first unscrewing a plastic cap to expose a long, narrow cloth streamer with a curved lead weight attached to the end. Upon release from the hand or projector the weighted streamer, would catch the air and quickly unwind from the top of the grenade, eventually

270:. When used in an "offensive" application such as the No. 69 grenade, where the user was not required to take cover before throwing, there was a chance that the user could be struck and injured by the fast-moving ball bearing. According to military author

to contact and ignite the detonator. Any impact in the horizontal axis would cause the ball bearing to follow the slope of the conical housing converting the horizontal acceleration into a vertical one, touching off the detonator as before.

The all-ways fuze was composed of a free-floating striker and detonator combination held apart by a weak spring. On top of this assembly was a steel

A ring of red "X" in the top half between the safety cap and middle indicated that it has a filling suitable for tropical use (humidity).
