Operators of modern weapons like the TOW missile, the UAV, and the drone are not new, and are highly effective in fighting off enemy threats.
But their ability to operate from safe, well-protected locations like urban centres has meant they are being increasingly deployed in far-flung locations and countries, and in conflict zones where civilians are a greater threat.
Operators of the modern warfare industry have come under increasing scrutiny in recent years, with the rise of drones and the proliferation of surveillance systems.
But what is opera music?
Operators like Tom Hagan and David Shaffer of the US Army were among the first to employ opera music as a sound effect for their aircraft.
In the early 1970s, opera composer Frank Zappa recorded a song called ‘Opera’ for the US Navy.
It was a popular piece that was played in the cockpit of a US aircraft and was also used in the opening credits of the 1969 film The Manchurian Candidate.
When the Vietnam War ended in 1975, opera was used by US forces in the campaign against North Vietnam, and was played on radio broadcasts during the final weeks of the war.
During the 1980s, the US military also employed operatic music as part of their training.
The US Air Force used opera to train pilots in the use of the aircraft, and some of its own pilots were trained to use the music to keep an eye on their enemies.
However, opera music is also a powerful tool for military operators who are looking to fight the enemy, and is used by some military forces around the world, including the People’s Liberation Army of China.
Opera music is played in many war-related situations, including when an enemy has breached a perimeter, a country is in chaos, or is trying to establish a foothold in a region.
In these circumstances, opera may be used as a distraction or a way of signalling to the enemy that the military is still on the ground and ready to take them on.
Operatic music has also been used by the US Airforce in the battle of Stalingrad, and it has been used in a number of training exercises over the past decade.
The Air Force’s website says opera is “one of the most recognizable sounds in warfare, and its use in war is almost universal, from parades to war games and war-themed films to operas”.
The music has been a source of much debate, with critics claiming that opera music can be very offensive and can cause people to lose concentration, while others argue that opera has a unique role in war.
There is a great deal of debate about opera in Australia and in the UK, where opera has been banned from many sporting events.
In Australia, opera is banned from sporting events that include football, cricket, basketball and rugby league.
However it is also banned from Australian National Theatre productions and opera companies.
In recent years opera has also come under scrutiny in the United States.
In May, the Department of Defense said it would not use opera to teach aircrew the art of combat, arguing that it was “an old-fashioned war story, and that its use is inappropriate”.
In September last year, the Obama administration announced that opera would not be used in training exercises in Afghanistan, and would instead be replaced by the Navy’s “war-fighting opera” in 2017.
In a statement on the Department’s website, the Navy said the decision “reflects our strong commitment to ensuring that the lessons and experiences we teach at sea are based on sound, the best science and the best art forms.”
The US Navy also said it was removing operas from its airshow programs “in order to ensure that our naval aviators can focus on the real threats and not the music”.
