WWW.SURVIVALEBOOKS.COM1-3. GeneralGrenades are small bombs of a size and shapeconvenient for throwing by hand or launching from a rifleor vehicle. The hand grenade is thrown by hand.However, some hand grenades may be launched from arifle grenade projection adapter and by a specialgrenade cartridge. The rifle grenade is launched by aspecial grenade cartridge from a rifle. Hand grenadesare used to supplement small arms against an enemy inclose combat, for producting a riot control agent, forsmoke screening and signaling, and for incendiarypurposes. Rifle grenades are used against armoredtargets, fortifications and personnel, and for screeningand signaling. Tables 1I and 1-2 contain a listing ofauthorized hand and rifle grenades, respectively. Table1-3 lists special type greandes.1-4. Hand Grenades.a. General. All <strong>Army</strong> hand grenades havepyrotechnic delay fuzes except for Grenades M68, M59(M33 with Fuze, M217) (M33A1), M57 and M26A2 whichare assembled with an impact-delay-type fuze. Agrenade assembled with a pyrotechnic delay fuze willnot function by impact action. A grenade assembledwith an impact-delay-type fuze will function on impactaction after an arming time of 1.6 seconds. If thegrenade fails to function on impact, the secondarypyrotechnic delay feature of the fuze will function thegrenade within 3 to 7 seconds.b. Types. There are five types of hand grenades(fig. 1-1):(1) Fragmentation hand grenades. Thesegrenades are used to produce casualties by highvelocity projection of fragment.(2) Illuminating hand grenade. This grenadeis used to provide illumination of terrain and targets.(3) Chemical hand grenades. Thesegrenades are used for incendiary, screening, signaling,training or riot control purposes.(4) Offensive hand grenade. This grenade isused for blast effect.(5) Practice and training hand grenades.These grenades are for training personnel in use, careTM 9-1330-200-12/TM 1330-12/1ASection II. DESCRIPTION AND FUNCTIONINGChange 7 1-2and handling of service grenades. Model designationsof the grenades are indicated in table 1-4.c. Functioning.(1) General. Release of the safety clip andremoval of the safety pin permit release of the safetylever. When the grenade is thrown, the safety lever isreleased and is forced away from the grenade body by astriker acting under the force of a striker spring. Thestriker rotates on its axis, and then strikes thepercussion primer, initiating the fuze. The grenade thenfunctions within the time shown in table 1-4.(2) Grenades M47 (fig. 1-2) and M48.Grenade fuze M227 is restrained from functioning by thesafety cotter pin, sliding safety latch, and handle. Theexhaust port seal is removed and discarded immediatelybefore pulling the safety cotter pin. When the safetycotter pin is removed and the safety latch is pushedrearward (fig. 1-3) from the lock pin, the handle isunlocked and the GRENADE IS ARMED. Releasing thehandle causes the arming pin spring to eject the armingpin. This releases the firing pin, allowing the firing pin toactivate the primer. The primer ignites the first-firemixture, which flashes and ignites the delay mixture.This, in turn, ignites the ignition mixture. The ignitionmixture burns through an aluminum foil shield on thebottom of the fuze and ignites the granulated CSpyrotechnic mixture in the grenade body. The burningmixture builds up pressure and opens the tape coveringthe exhaust port. This pressure also forces release ofCS from the grenade, while jet action causes thegrenade to move quickly and erratically along theground. The M48 functions in the same manner as theM47, except that the M48 emits red smoke.1-5. Rifle Grenadesa. General. Rifle grenades (fig. 1-4) are finstabilized.They are launched from a rifle. Thepropelling force for the grenade is provided by a specialgas-producing grenade cartridge, which is loaded intothe rifle chamber. Rifle grenades
