More than 100,000 police and military personnel are currently deployed as United Nations peacekeepers (known as  Blue Helmets) in 16 UN peacekeeping operations, with one in four of these peacekeepers deployed in South Sudan or Sudan. Between 2004 and 2014 there were at least 22 notable incidents of diversion or loss of weapons and ammunition during peacekeeping operations in these countries. These incidents, each of which involved the loss more than 10 weapons or more than 500 rounds of ammunition, have occurred during patrols, during attacks on convoys, and on fixed sites.

The looting of Libya’s massive stocks of weapons and ammunition was one of the most significant arms proliferation events of the 21st century. Anti-government forces seized tens of thousands of small arms, light weapons and other munitions, and thousands more were left unguarded in abandoned storage facilities. These weapons have fuelled crime and conflict in Libya and throughout North Africa.

This Research Note summarizes the findings of a chapter on floating armouries in the Small Arms Survey 2015: Weapons and the World. It presents basic information on the number of floating armouries operating in the HRA, their use, the number of arms they store, and an overview of some of the nascent—and potential—approaches to regulating floating armouries to ensure safe and secure practices.

The increasingly sophisticated arsenals of guided light weapons held by non-state actors pose an international security threat. Such systems—man-portable air defence systems (MANPADS) and anti-tank guided weapons (ATGWs)— are operable by a single user or a small crew, and the weapons' missiles are either manually targeted or self-guided after launch. These weapons have been used by armed groups to attack commercial airlines, military aircraft, and governmental targets, as well as to degrade military and peacekeeping operations worldwide.

Improvised explosive devices (IEDs), which are increasingly used by insurgents, have devastating effects on government forces and civilians. Between 2011 and 2013, more than 4,300 IED events in 66 countries resulted in an estimated 65,400 casualties, the vast majority of them civilian.

Four countries—Iraq, Pakistan, Afghanistan, and Syria—bear an especially high incidence of IED attacks, accounting for a total of more than 3,300 incidents and more than 51,000 casualties during that period.

Policy and research dealing with the relationship between women and firearms usually stress the role of women as victims. Of the estimated 66,000 annual homicides of women committed each year, roughly 40 percent involve firearms. Guns are even more commonly used to injure, intimidate, and coerce women.

Although some women own and use guns, policy and research on firearms tend to focus on the role of and effects on men.

Levels of handgun ownership and armed violence remain high in the Western Balkans region, despite decreased threat of armed conflict during the past fifteen years. Pervasive civilian ownership of firearms has been linked to elevated violent crime, and the homicide rate in the Western Balkans is higher than those of nearby countries. In addition, organized crime activities contribute to insecurity in the region.

Unplanned explosions at munitions sites (UEMS) are a significant safety concern for governments and a major security challenge for the international community. The Small Arms Survey has documented more than 500 such incidents in 100 countries over the 35-year period from 1979 to 2013.

South Sudan is saturated with weapons following the long civil war prior to its independence in 2011. The weapons that were once in the hands of the rebel forces now officially belong to the newly developed state defence and security forces. In comparable situations elsewhere, a by-product of restructuring such forces is a surplus of small arms, light weapons, and ammunition. The demand for armed personnel and weaponry is clearly at its height during periods of conflict. As conflicts abate, however, many arms remain in circulation.

While the weapons of state armed forces are not the largest major category of small arms—worldwide there are around three civilian-owned firearms for each one held by militaries—they are a serious factor in conflict and violence, and the focus of much international diplomacy. Military-owned small arms also constitute the world’s largest centrally controlled stockpiles. They can be involved in massive transfers, and raise vital control issues.
