Types THERE ARE VARIOUS TYPES OF GRENADES, THAT ALL HAVE DIFFERENT STRUCTURES AND USES. HERE ARE SOME EXPLAMES . . .

Fragmentation Casing fragments during explosion, shrapnel causes major damage.

Concussion The majority of damage is caused by the explosvie force of the bomb alone.

Anti-tank Used to pierce through thick armoured vehicles. However, they are often not very effective.

Stun Generates non-lethal bright light and very loud sound in order to disorentate the target.

Smoke Releases thick smoke to impair vision, or chemicals that can damage by corrosion or burning.

Incendiary Contains flammable materials that ignite either by a fuse or on contact with oxygen. Used to set fires.

Sting Expells small rubber balls at high velocity in order to cause pain but not permanent damage.

Molotov Cocktail Utilises any flammable liquid, ignited by an improvised rag fuse. Not often used in military combat.

THE MILLS BOM WAS THE FIRTS GRENADE TO INCLUDE A SAFETY PIN IN ITS DESIGN. ONCE IT IS REMOVED THE DETONATION OF THE DEVICE IS ESSENTIALY IMPOSSIBLE TO AVOID. ONCE THE FUSE IS LIT THERE IS NOTHING TO BE DONE.

LA U ONCE THE GRENADE IS THROWN NOTHING PREVENTS THE SAFETY LEVER FROM BEING EJECTED.

THE BOLT IS MOVED BY A STRING , RELEASING THE STRIKER.

WHEN THE STRIKER HITS THE PERCUSSION PLATE A SPARK IS CREATED.

FUSE BEGINS T

TO BURN WHEN THE WICK IS IGNIGHTED BY THE SPARK.

ONCE THE FUSE BURNS DOWN ITS SETS OFF THE DETONATOR.

BLAST WAVE CREATES HIGHLY COMPRESSED AIR PARTICLES.

FRAGMENTATION THROWS SHRAPNEL OUTWARDS

SECONDARY EXPLOSIONS INTENSE HEAT CAN CAUSE SECONDARY EXPLOSIONS / FIRES.

SHOCK WAVE CARIES ENERGY THROUGH THE MEDIUM.

HEAT AND FIRE EXPLOSION CREATES HEAT AND FIRE.

BLAST WIND CREATES A VACUM THAT REFILLS ITS SELF WITH AIR AND PULLS SHRAPNEL BACK IN.
