This grenade closely resembles the high explosive stick grenade 24 in external form and size. However, instead of the high explosive filling this grenade is filled with a smoke mixture. There are eight holes in the base of the head through which the smoke escapes. The handle has three horizontal corrugations at the screw cap end to assist in differentiation by touch. Upon activation, smoke is emitted for a period of two minutes, forming an effective screen for machine gun nests and pillboxes.

This is a thin-cased offensive type grenade with a B. Z. E. friction igniter screwed into the top. The cylindrical body is made of aluminum and painted yellow. There are two models of this grenade, one 3 5/8 inches long and the other 4 inches long. This grenade may also be used as a booby trap by the insertion of a D. Z. 35 Pressure Igniter. To operate the grenade, the head of the igniter is unscrewed and pulled, drawing the wire through the friction composition and igniting the delay pellet. The grenade is then thrown and after a 4-5 second delay, the delay element initiates the detonator.
This grenade consists of a thin egg-shaped case filled with an explosive charge, and a friction type igniter with a delay pellet. The upper end of the friction wire in the igniter is attached to a disc in the head which screws on to the top of the body. In operation, the head is unscrewed and pulled, drawing the wire through the friction composition and igniting the delay pellet. After a delay of from 4 to 5 seconds the pellet initiates the detonator which in turn sets off the explosive filler.
The head of this grenade is a thin steel casing containing the explosive filler. This is screwed onto a hollow wooden handle through the center of which runs a double length of cord. This cord connects at the forward end to a friction pull igniter (B. Z. 24) and at the rear to a porcelain ball in a metal cap. In operation, the cap is removed, the porcelain ball pulled, and the missile thrown to detonate after a 4-5 second delay.
This grenade, a new type of offensive weapon, has no outer casing or cover, but consists merely of a disc cut from a pre-cast or pressed pellet of explosive, and an igniter. The disc, which is believed to be R.D.X./wax, is 3 5/16 inches in diameter and 17/32 inches thick. It is drilled to receive the igniter and detonator.
The two standard German rifle dischargers are the cup type (Schiessbecher) and the spigot type. The former is made of steel and consists of a rifled barrel which screws into a holder fitted with a clamp for attaching it to the rifle barrel. There are no gas ports, and varying ranges are obtained by altering the elevation of the rifle by the aid of the sighting attachment. The latter type consists of a hollow tubular spigot about one inch in diameter, terminating in a part resembling the hilt of a bayonet. It is fitted to the rifle in the same manner as a bayonet, and is locked in position by a spring-loaded bolt. The hollow tailpiece of the grenade is fitted over the spigot, and on firing the propelling cartridge, the gasses pass out of the barrel of the rifle through the spigot and into the hollow tailpiece to propel the grenade. Both a swing-over blade front sight and a rear sight are provided.
Two additional H.E.A.T. (hollow charge) armor piercing rifle grenades have recently been recovered and are illustrated herewith. They bear the designations 
This grenade consists of a bell-shaped body of thin steel with a slightly convex aluminum closing disc, a graze fuze which screws into a cylindrical projection welded to the base of the body, and a finned tail unit. The bursting charge of cyclonite wax is cast around an aluminum hollow charge liner which is hemispherical in shape. A detonator and intermediary exploder are contained in an aluminum magazine which fits into the base of the main explosive cavity. The tail unit screws onto the base of the fuze housing and consists of a drawn-steel tube with six vanes formed in pairs. The cartridge is of the 7.92 mm small arm type with an undyed hollow wooden bullet.
