WEAPONS TRADE
The arms dealing consists in furnishing with weapons or with ammunition an entity (group fighting, criminal association, state) by violating international regulations on arms sales. Its definition remains unclear, many arms sales being made on the "gray market" of weapons.

According to the UN, the arms trade is one of the three most lucrative illegal activities with drug trafficking and prostitution. The international market for arms trafficking is estimated at 1200 billion dollars per year.

So, they represented 4,4 % of the French total exports between 1980 and 1988 and 4,8 % for the United Kingdom.
In 2005 the annual report of the Congress of the United States on arms sales in the world considered that in 2004 the total value of the sale contracts of weapons (and any associated services) worldwide was 37 billion dollars, while previous year it was 28,5 billion dollars.
