There are two types:
No. 1. Service grenades.
No. 2. Improvised or home-made grenades.
These are again divided into two classes:
=A.= Those that depend for their effect upon fragmentation on
detonation.
=B.= Those that depend for their effect upon the shock of detonation
only.
The type =B= is more commonly met with than type =A=. Ignition is by
time or percussion. The time of fuses about six seconds burning.
=Precautions.= When handling foreign grenades care should always be
taken and the following rules should be enforced:
1. Only skilled grenadiers should be allowed to examine
and handle any grenades found.
2. Grenade depots when discovered should be immediately
reported to the nearest grenadier.
3. Foreign time grenades should be thrown as soon
as the lighting device has been started.
