The Joint Chiefs of Staff (JCS) is the body of the most senior uniformed leaders within the United States Department of Defense, which advises the president of the United States, the secretary of defense, the Homeland Security Council and the National Security Council on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of a chairman (CJCS), a vice chairman (VJCS), the chiefs of the Army, Marine Corps, Navy, Air Force, Space Force, and the chief of the National Guard Bureau. Each of the individual service chiefs, outside their JCS obligations, works directly under the secretaries of their respective military departments, e.g. the secretary of the Army, the secretary of the Navy, and the secretary of the Air Force.
The United States Strategic Command (USSTRATCOM) is one of the eleven unified combatant commands in the United States Department of Defense. Headquartered at Offutt Air Force Base, Nebraska, USSTRATCOM is responsible for strategic nuclear deterrence, global strike, and operating the Defense Department's Global Information Grid. It also provides a host of capabilities to support the other combatant commands, including integrated missile defense; and global command, control, communications, computers, intelligence, surveillance, and reconnaissance (C4ISR). This command exists to give "national leadership a unified resource for greater understanding of specific threats around the world and the means to respond to those threats rapidly".
The Air Staff is one of the Department of the Air Force's two statutorily designated headquarters staffs: the other staff is the Office of the Secretary of the Air Force, also known as the Secretariat.

The Air Staff is primarily composed of uniformed United States Air Force officials who assist the Chief of Staff in carrying out his dual-hatted role: as the principal military advisor to the Secretary of the Air Force, and as a member of the Joint Chiefs of Staff.
The J-class submarines were seven submarines developed by the Royal Navy prior to the First World War in response to claims that Germany was developing submarines that were fast enough to operate alongside surface fleets. Six were completed during mid-1916, while a seventh entered service at the end of 1917.
One Station Unit Training, sometimes referred to as One Site Unit Training, is a term used by the United States Army to refer to a training program in which recruits remain with the same unit for both Basic Combat Training (BCT) and Advanced Individual Training (AIT). Immediately following Basic Training, the unit seamlessly transforms from a BCT unit into an AIT unit. There is no relocation and the same Drill Sergeants who conducted the Basic Training will continue to instruct all of the participating recruits in their Advanced Individual Training. This streamlines the training schedule and helps to produce more camaraderie between trainees. There are a variety of Military Occupational Specialties (MOS) and training stations that have OSUT training, such as:

A smart motorway, also known in Scotland as an intelligent transport system, is a section of motorway in the United Kingdom that employs active traffic management (ATM) techniques to increase capacity through the use of MIDAS technology including variable speed limits and occasionally hard shoulder running and ramp metering at busy times. They were developed at the turn of the 21st century as a cost-effective alternative to traditional carriageway widening, with intended benefits ranging from more reliable journey times to lower vehicle emissions. However, despite the risk of a collision occurring between two moving vehicles being found to be decreased, there has been an acknowledged rise in the incidence of collisions involving vehicles where at least one was stationary in the first few years following the widespread removal of the hard shoulder on the country's busiest sections of motorway. Smart motorways garnered intense criticism from politicians, police representatives and motoring organisations, particularly from 2020 onwards, after a surge in near miss incidents and dozens of fatalities were revealed, and as of April 2023, no new smart motorways will be built.
