Armado (Span). Fleet, Navy Armo da fuoco (Ital). Firearm gun Armament is the aggregate of a nation s military strength, which includes all the items used by the Army, Navy and Ait Force (ships, aircraft weapons, ammunition, expis, tanks, transportation, etc), as well as the personnel to man them. It also includes all military installations (fortifications, barracks, ammo magazines, etc) and all industries working for war purposes... 

The Federal Firearms Act of 1938 (R L. No. 75-785) required that all dealers who buy or sell weapons across state lines hold a Federal Firearms License (FFL). The Gun Control Act of 1968 (P. L. No. 90-618) superseded the 1938 law. It increased license fees and prohibited most sales of firearms or ammunition across state lines. All gun dealers now had to be licensed and had to record all sales of firearms or ammunition so that they could be traced by police. Maximum penalties were raised to 5,000 and imprisonment for five years. 

Wood bullets are often used in blank ammunition where automatic weapon functioning is required. They can be lethal at short range if some form of bullet breakup device is not fitted to the muzzle of the firearm. Some wood bullets may be sabots for subcaliber projectiles. 

With rapid advances in technology there is no doubt that firearms and ammunition will continue to develop and it is not beyond the realm of possibility that firearms could be replaced by some other form of handheld weapon. 

Firearms and their associated ammunition, spent bullets, and spent cartridge cases provide useful information for identifying suspects, terrorist groups, and the criminal history of a weapon. Unfortunately, despite the numerous detailed books on the physical aspects of firearms, very little has been published on the chemical aspects, and what has been published is sparse and fragmented.

Examination of gunshot residue (GSR) plays an important role in establishing some circumstances of a crime involving use of a firearm. This kind of examination is complementary to ballistic examination of weapons and ammunition. 

Also using MC-ICP-MS, Zeichner et al. investigated possible memory effects derived from shooting bullets [13], It was concluded that no mechanical or chemical method completely removes lead deposits from the barrels of firearms. That obviously makes the identification of bullets much more difficult, since the isotopic composition of a bullet fragment could be affected by those from bullets shot earlier from the same weapon. Still, the authors indicated that if the ammunition brands involved (bullets and primers) in a shoot-out incident differ significantly in their original isotopic composition, it should be possible to find out which ammunition or firearm was responsible for a particular gunshot entry.
