A balaclava, also known as a monkey cap, balaclava helmet, ski mask or shiesty, is a form of cloth headgear designed to expose only part of the face, usually the eyes and mouth. Depending on style and how it is worn, only the eyes, mouth and nose, or just the front of the face are unprotected. Versions with enough of a full face opening may be rolled into a hat to cover the crown of the head or folded down as a collar around the neck.

HMS Havock was an H-class destroyer built for the British Royal Navy in the mid-1930s. During the Spanish Civil War of 1936–1939, the ship enforced the arms blockade imposed by Britain and France on both sides as part of the Mediterranean Fleet. During the first few months of the Second World War, Havock searched for German commerce raiders in the Atlantic Ocean and participated in the First Battle of Narvik during the Norwegian Campaign of April–June 1940 before she was transferred back to the Mediterranean Fleet in May where she escorted a number of convoys to Malta. The ship took part in the Battle of Cape Spada in July 1940, the Battle of Cape Matapan in March 1941 and the evacuation of Greece in April 1941. She was damaged during the Battle of Crete the following month, but participated in the Syria–Lebanon Campaign in June.

HMS King George V was the lead ship of the five British King George V-class battleships of the Royal Navy. Laid down in 1937 and commissioned in 1940, King George V operated during the Second World War in all three major naval theatres of war, the Atlantic, Mediterranean and Pacific, as well as part of the British Home Fleet and Pacific Fleets. In May 1941, along with HMS Rodney, King George V was involved in the hunt for and pursuit of the German battleship Bismarck, eventually inflicting severe damage which led to the German vessel's sinking. On 1 May 1942 the destroyer HMS Punjabi sank after a collision with King George V in foggy conditions. King George V took part in Operation Husky and bombarded the island of Levanzo and the port of Trapani. She also escorted part of the surrendered Italian Fleet, which included the battleships Andrea Doria and Duilio, to Malta. In 1945 King George V took part in operations against the Japanese in the Pacific.

HMS Prince of Wales was a King George V-class battleship of the Royal Navy that was built at the Cammell Laird shipyard in Birkenhead. Despite being sunk less than a year after she was commissioned, Prince of Wales had an extensive battle history, first seeing action in August 1940 while still being outfitted in her drydock when she was attacked and damaged by German aircraft. In her brief career, she was involved in several key actions of the Second World War, including the May 1941 Battle of the Denmark Strait where she scored three hits on the German battleship Bismarck, forcing Bismarck to abandon her raiding mission and head to port for repairs. Prince of Wales later escorted one of the Malta convoys in the Mediterranean, during which she was attacked by Italian aircraft. In her final action, she attempted to intercept Japanese troop convoys off the coast of Malaya as part of Force Z when she was sunk by Japanese aircraft on 10 December 1941, two days after the attack on Pearl Harbor.

HMS Repulse was one of two Renown-class battlecruisers built for the Royal Navy during the First World War. Originally laid down as an improved version of the Revenge-class battleship, her construction was suspended on the outbreak of war because she would not be ready in time. Admiral Lord Fisher, upon becoming First Sea Lord, gained approval for her to resume construction as a battlecruiser that could be built and enter service quickly. The Director of Naval Construction (DNC), Eustace Tennyson-d'Eyncourt, quickly produced an entirely new design to meet Admiral Lord Fisher's requirements and the builders agreed to deliver the ship in 15 months. They did not quite meet that ambitious goal, but the ship was delivered a few months after the Battle of Jutland in 1916. Repulse and her sister ship Renown were the world's fastest capital ships upon completion.

HMS Hood was a battlecruiser of the Royal Navy (RN). Hood was the first of the planned four Admiral-class battlecruisers to be built during the First World War. Already under construction when the Battle of Jutland occurred in mid-1916, that battle revealed serious flaws in her design, and despite drastic revisions she was completed four years later. For this reason, she was the only ship of her class to be completed, as the Admiralty decided it would be better to start with a clean design on succeeding battlecruisers, leading to the never-built G-3 class. Despite the appearance of newer and more modern ships, Hood remained the largest warship in the world for 20 years after her commissioning, and her prestige was reflected in her nickname, "The Mighty Hood".

Nomex is a flame-resistant meta-aramid material developed in the early 1960s by DuPont and first marketed in 1967.

HMS Cornwall, pennant number 56, was a County-class heavy cruiser of the Kent sub-class built for the Royal Navy in the mid-1920s. The ship spent most of her pre-World War II career assigned to the China Station. Shortly after the war began in August 1939, she was assigned to search for German commerce raiders in the Indian Ocean. Cornwall was transferred to the South Atlantic in late 1939 where she escorted convoys before returning to the Indian Ocean in 1941. She then sank the German auxiliary cruiser Pinguin in May. After the start of the Pacific War in December 1941, she began escorting convoys until she was transferred to the Eastern Fleet in March 1942. The ship was sunk on 5 April by dive bombers from three Japanese aircraft carriers during the Indian Ocean Raid.

A flight suit is a full-body garment, worn while flying aircraft such as military airplanes, gliders and helicopters. These suits are generally made to keep the wearer warm, as well as being practical, and durable. Its appearance is usually similar to a jumpsuit. A military flight suit may also show rank insignia. It is sometimes used as a combat uniform in close quarters battle or visit, board, search, and seizure situations, for its practicality.

A hazmat suit is a piece of personal protective equipment that consists of an impermeable whole-body garment worn as protection against hazardous materials.

Operation Outward was a British campaign of the Second World War that attacked Germany and German-occupied Europe with free-flying balloons. It made use of cheap, simple balloons filled with hydrogen and carrying either a trailing steel wire to damage high voltage power lines by producing a short circuit, or incendiary devices to start fires in fields, forests and heathland. A total of 99,142 Outward balloons were launched; about half carried incendiaries and half carried trailing wires.

The Attacker class were a class of escort aircraft carriers in service with the British Royal Navy during the Second World War.

HMS Hardy was the flotilla leader for the H-class destroyers, built for the Royal Navy in the mid-1930s. During the Spanish Civil War of 1936–1939 the ship spent considerable time in Spanish waters, enforcing the arms blockade imposed by Britain and France on both sides of the conflict. Hardy was transferred to Freetown, Sierra Leone, in October 1939 to hunt for German commerce raiders in the South Atlantic with Force K. After returning to the United Kingdom in early 1940, the ship became flagship of the 2nd Destroyer Flotilla assigned to the Home Fleet. During the Norwegian campaign of 1940, Hardy participated in the First Battle of Narvik where she sank one German destroyer. As the British ships were withdrawing, they were discovered by two other German destroyers that so badly damaged Hardy that she had to be run aground to stop her from sinking. The ship was lifted by a rising tide and eventually capsized.

The Garda Public Order Unit – commonly known as the Garda Riot Squad – is a unit of the Garda Síochána, Ireland's police force, that deals with public disorder, including riots and protests.

USS Oberrender (DE-344) was a John C. Butler–class destroyer escort built for the United States Navy during World War II. She was named for Lieutenant Commander Thomas Olin Oberrender Jr., the engineering officer of the light cruiser USS Juneau, who was killed when that ship was torpedoed and sunk during the Naval Battle of Guadalcanal in 1942.

HMS Kipling (F91) was a K-class destroyer built for the Royal Navy during the 1930s.
