Do frag grenades actually cause an explosion (IE fireball) or is it JUST a bunch of shrapnel being expelled?

Thanks :p

A frag gernade would have a fireball but the fire is not what does the damage it is the fragments of the gernade casing that do the damage. So they would cause a bright explosion probably a yellow to red color.

With Frag Grenades (either system), the primary blast radius would be explosion and shrapnel, but anything after that is pure shrapnel.

Are you talking ingame or real life? In real life, there is no mini-nuke reaction like you see in the movies; only a very loud boom, a decent-sized shockwave, lots of shrapnel and maybe a mini-fireball (gone VERY quickly.)

Now if you want a fireball grenade in your game then go for it...

A frag grenade has a small amount of explosive power. When one is detonated the explosion makes the metal casing fragment into small super hot pieces of deadly metal that will b quite painful and often deadly. The actual blast is not too powerful, say for instance a person were to jump on a grenade the blast woud be most likely contained. It would however cause a very grusome death for that individual.

aren't frag grenades and the lumpy speghetti sauce they create fun??? :) if you want big fireball try a white phosphorous or (Willie peter as they are sometimes refered to) or a thermite grenade. :)

Frag grenades do not create a visible explosion of color unless viewed at night. During the day, a grenade exploding usually displaced loose materials on the surface of the ground, creating a small cloud of dust. At night, the flash of light from a grenade lasts a fraction of a second and then is gone.

I have not seen a an accurate representation of a grenade on TV or movie. Most show large fireball type of explosions and people flying everywhere. The concussive blast from a grenade will affect a person out to about 10 meters diameter (30 feet approx.) but isn't really strong enough to make a person fly like they do in the movies. Someone close to a grenade, and off balance, would be knocked down, but not thrown any distance. Heck, someone not expecting a grenade could be knocked down, but again...not thrown any distance. Shrapnel from a frag grenade can reach out as far as 15 meters diameter from the grenade explosion. These little buggers hurt like the dickens when they hit you, and as they are hot and quick moving, they can kill.

AsDurian mentioned, WP grenades do a lot better at creating a sort of "fireball", though it's not like the Hollywood frag grenade type of explosion. It's more akin to a fireworks explosion, with the fragments of white phosphorous being strewn across a wide area (12 meters diameter about). The white phosphorous burns INCREDIBLY hot, and water doesn't put it out. These grenades are great for starting fires.

Thermite grenades don't explode any sizable distance, but they, too, burn incredibly hot. These grenades are excellent at burning through things like concrete, steel, engine blocks, whatever is underneath them essentially. No concussive blast emits from a thermite.

Hope this helps some.

The new movie Black Hawk Down has pretty realistic examples of frag grenades -- though they only use them a couple of times. A small "explosion" of dirt and a lot of dust. I'm also pretty sure they use some WP grenades to destroy/deny the downed blackhawk helicopters.

Another example of a pretty realistic representation of grenades (albiet WWII) is the HBO mini-series Band of Brothers.

In the actual situation at somalia (I have read the book Black Hawk down) they used thermite grenades- standard procedure, apparently, on equipment they don't want falling into enemy hands. The helecopters seemed to actually explode in the movie, although I think that was just because it's quicker than what really happens, which is the thing burns, not blows up.

yep thermites were used to destroy the two mh60l's and mixing thermites with jp-5 fuel is a rather interesting mess.

and as stated earlier the only time to safely(as in if you saw it you were waaaay too close) see a flash is seen is in lowlight conditions.
