DHS Aging and Failing Infrastructure Report: Dams

DHS-CollapsingDams

Dam safety incidents can occur at any point during a dam’s lifetime, but the most common period of dam failure is the first 5 years of operation. The United States Society of Dams conducted a study in 2009 of 1,158 national and international dam failures and safety incidents and found that 31 percent of safety incidents occur during construction or within the first 5 years of operation. The most common causes of failure are overtopping, piping, and foundation defects. Overtopping caused by flooding and high-water events accounts for 34 percent of dam failures in the United States. Erosion caused by overtopping can compromise embankments and lead to failure. The risk of overtopping increases if the spillway design is inadequate, debris causes spillway blockage, or the dam crest settles.

DHS Aging and Failing Infrastructure Report: Navigation Locks

DHS-FailingLocks

Most locks are designed to last for 50 years, but 54 percent of IMTS locks are more than 50 years old, and 36 percent are more than 70 years old. Many of these locks are in need of repair and replacement, and some lack basic maintenance. Concrete is crumbling at some locks, and some have not been painted in 25–30 years, increasing the risk of corrosion. Locks lacking maintenance or in need of repair and replacement are more likely to have unscheduled closures. Unscheduled closures are more costly than scheduled closures, because vessel operators and companies are unable to plan to offset the delays from these incidents. The annual number of unscheduled lock closures has steadily increased since 1992. Fewer than 7,000 unscheduled closures occurred every year before 2000, and more than 7,000 occurred every year after 2000, peaking in 2008 with 13,250.

DHS Reference Aid on Illicit Uses of Drones and Model Aircraft

OCIA-ModelAircraft

Model Aircraft are custom built or commercially produced unmanned aircraft systems (UAS) that meet the statutory definition of Model Aircraft and operate in accordance with the statutory requirements for Model Aircraft. These are sometimes referred to as radio controlled airplanes or aircraft and usually require one individual for operational control. Some Model Aircraft are capable of sustained flight for approximately 2 hours or less depending on the type of Model Aircraft (Rotary or Fixed Wing) and power source (e.g. nitromethane, lithium ion, and lithium polymer batteries). Model Aircraft must be flown within visual line of sight of the operator; however, there is an increasing use of first person view technology that allows operation to occur beyond line of sight and at altitudes in excess of several hundred feet.

OSAC Bulletin: Mustard Agent Likely Used in ISIL Attack in Iraq August 2015

OSAC-MustardAttackISIL

Early tests show that the Islamic State of Iraq and the Levant (ISIL) used chemical agents during an attack on Kurdish Peshmerga forces on August 11 in Makhmour, Iraq. U.S. government officials reported that preliminary tests on shell fragments indicated a presence of chemical agents, although additional analyses would be necessary to determine the full composition. Early media reports have pointed to the use of mustard agent. Overall, ISIL’s use of mustard agent appears to be largely undeveloped – although the group is likely seeking to advance its capabilities – and there is no evidence that they have used mustard agent (also known as mustard gas) against civilian interests at this point.

Restricted U.S. Army Cryptologic Linguist Training Manual

USArmy-CryptologicLinguist_Page_001

This publication is for soldiers holding military occupation specialty (MOS) 98G and their trainer/first-line supervisor. It contains standardized training objectives in the form of task summaries that support unit missions during wartime. Soldiers holding MOS 98G should be issued or have access to this publication. It should be available in the soldier’s work area, unit learning center, and unit libraries. Trainers and first-line supervisors should actively plan for soldiers to have access to this publication. It is recommended that each 98G soldier be issued an individual copy.

Restricted U.S. Army Foreign Internal Defense Manual

USArmy-ForeignInternalDefense

FID is participation by civilian and military agencies of a government in any of the action programs taken by another government or other designated organization to free and protect its society from subversion, lawlessness, insurgency, terrorism, and other threats to its security (Joint Publication [JP] 3-22, Foreign Internal Defense). This publication depicts the integrated theater efforts that include ARSOF and conventional forces roles in joint, multinational, intergovernmental, and nongovernmental organizations working in a collaborative environment. It provides an overview of selected sources of power applied through the instruments of national power brought to bear for supporting FID and the impact and interaction of Army units with the other instruments of national power. In addition, it illustrates how FID is a key component of a host nation’s (HN’s) program of internal defense and development (IDAD), and that the focus of all U.S. FID efforts is to support that IDAD program to build capability and capacity to free and protect the HN from subversion, lawlessness, and insurgency.

Restricted U.S. Navy Intelligence Support to Naval Operations Manual NWP 2-01

USNavy-IntelSupportNavalOps

NWP 2-01 is a comprehensive reference detailing the intelligence support available to the naval commander in the successful planning and execution of operations. NWP 2-01 is by nature a refresher and ready resource for the Information Dominance Corps (IDC) intelligence professionals, information warfare officers, and cryptologic technicians; however, the target audience is the operational commander. The publication’s length and content are specifically tailored to ensure a practical and valuable reference for the operational decision maker. NWP 2-01 is the foundation for a series of proposed follow-on Navy tactics, techniques, and procedures (NTTP) publications.

Restricted U.S. Navy Special Warfare Manual NWP 3-05

USNavy-SpecialWarfare_Page_001

This navy warfare publication describes the nature, forces, organization, and employment of naval special warfare (NSW). Naval special warfare is a relatively small, maritime special operations force (SOF) consisting of approximately 9,250 personnel: 2,700 sea-air-land commandos (SEALS), 700 special warfare combatant-craft crewmen (SWCCs), 750 Reservists, 4,000 combat support (CS) and combat service support (CSS) personnel, and more than 1,100 civilians. NSW constitutes 11 percent of special operations forces and less than 2 percent of United States Navy (USN) forces. NSW costs 3/10ths of one cent (0.3 percent) of every United States (U.S.) defense dollar.

Restricted U.S. Army Special Operations Forces Manual

FM 3-18 is the principal manual for Special Forces (SF) doctrine. It describes SF roles, missions, capabilities, organization, mission command, employment, and sustainment operations across the range of military operations. This manual is a continuation of the doctrine established in the JP 3-05 series, ADP 3-05, ADRP 3-05, and FM 3-05.

(U//FOUO) Marine Corps Intelligence Activity Mauritania Cultural Field Guide

MCIA-MauritaniaCultureGuide

Mauritania is the westernmost country in the Sahel region. Its location between Arab-influenced North Africa and Sub-Saharan Africa has created some ethnic divides and tensions between people of Arab origin and the indigenous populations. In other cases, the population has become united under a common belief; nearly all Mauritanians are Muslim. Most of the country is desert, making life in Mauritania difficult. In the past, northern populations were nomadic herders and the southern populations were sedentary farmers. Many continue these lifestyles today, but desertification and droughts have severely reduced the amount of fertile land in Mauritania.This has hurt herders and farmers. Many have had to abandon their lifestyles to attempt make a living in the cities. As a result, most Mauritanian cities are overcrowded and have high unemployment rates.
