The Sikorsky UH-60 Black Hawk is a four-bladed, twin-engine, medium-lift utility helicopter manufactured by Sikorsky Aircraft. Sikorsky submitted the S-70 design for the United States Army's Utility Tactical Transport Aircraft System (UTTAS) competition in 1972. The Army designated the prototype as the YUH-60A and selected the Black Hawk as the winner of the program in 1976, after a fly-off competition with the Boeing Vertol YUH-61.
The UH-60A entered service with the U.S. Army in 1979, to replace the Bell UH-1 Iroquois as the Army's tactical transport helicopter. This was followed by the fielding of electronic warfare and special operations variants of the Black Hawk. Improved UH-60L and UH-60M utility variants have also been developed. Modified versions have also been developed for the U.S. Navy, Air Force, and Coast Guard. In addition to U.S. Army use, the UH-60 family has been exported to several nations. Black Hawks have served in combat during conflicts in Grenada, Panama, Iraq, Somalia, the Balkans, Afghanistan, and other areas in the Middle East.

Military Coast Guard A military is an organization authorized by its greater society or the state to use lethal force, usually including use of weapons, in defending its country or state institutions by combating actual or perceived threats. The military may have additional functions of use to its greater society, such as advancing a political agenda e.g. military junta, supporting or promoting economic expansion through imperialism, and as a form of internal social control. As an adjective the term "military" is also used to refer to any property or aspect of a military. Militaries often function as societies within societies, by having their own military communities.
The profession of soldiering as part of a military is older than recorded history itself. Some of the most enduring images of the classical antiquity portray the power and feats of its military leaders. The Battle of Kadesh in 1274 BC was one of the defining points of Pharaoh Ramesses II's reign and is celebrated in bas-relief on his monuments. A thousand years later the first emperor of unified China, Qin Shi Huang, was so determined to impress the gods with his military might that he was buried with an army of terracotta soldiers.[1] The Romans were dedicated to military matters, leaving to posterity many treatises and writings as well as a large number of lavishly carved triumphal arches and victory columns.

TOS-1A In Exercise Parade TankTOS-1 (Russian: ТОС-1 - тяжёлая огнемётная система, English: Heavy Flame Thrower System) is a Soviet 220mm 30-barrel (original system, Ob.634 or TOS-1M) or 24-barrel (Ob.634B or TOS-1A) multiple rocket launcher and thermobaric weapon mounted on a T-72 tank chassis. TOS-1 was designed for defeating enemy personnel in fortifications, in open country, and in lightly armoured vehicles and transport. First combat tests took place in 1988-1989 in the Panjshir Valley during the Soviet war in Afghanistan. The TOS-1 was shown for the first time in public in 1999 in Omsk.
Angara Rocket Mock-Up Installed on the Launch Pad
RIA Novosti – A full-scale mock-up of Russia’s first large post-Soviet rocket has been rolled out to a launch pad at the Plesetsk space center.
The mock-up of the Angara, built by the Khrunichev aerospace research and production center, will be used to test ground support systems ahead of the maiden launch of the vehicle scheduled for later this year.
The Angara is expected to launch both government and commercial satellites either as a single rocket or in several configurations of booster stages clustered together for heavier payloads.
The modular launcher will be able to cover a wide range of payload classes now served by rockets built by a number of Russian manufacturers, including the Proton, the country’s largest booster.
The engine developed for the Angara will burn kerosene and liquid oxygen, which is deemed by an order of magnitude more environmentally friendly than the toxic hydrazine used in the Proton.
The environmental impact of that rocket has soured relations between Russia and Kazakhstan, which leases the Baikonur space center to Russia for $115 million per year.
Russia is building a launch complex for the Angara at the country’s new Vostochny space center in the Far East to reduce dependence on Kazakhstan for space launches.
The Angara will complement the country’s venerable Soyuz manned rocket, currently the only vehicle in the world capable of launching astronauts to the International Space Station.
Last month, Oleg Ostapenko, the head of Russia’s space agency Roscosmos, said that a decision would be made in the near future about building a new super-heavy rocket that would be, in its expanded form, the largest in world history.
