They were first used by the US in the Civil War for observation. Messages were sent via telegraph on a line attached to one of the tie down cables. However many commanders did not trust the newfangled gadgets. Other countries probably used them earlier.
The first use of hot air balloons was in the American Civil War for surveillance of troop movements.
During World War I, hot air balloons were primarily used by military forces for reconnaissance and artillery spotting. The French Army was one of the most prominent users, employing balloons to gather intelligence on enemy positions. The British Royal Flying Corps also utilized hot air balloons for similar purposes, although they gradually transitioned to more advanced aircraft for aerial observation as the war progressed. Overall, these balloons played a critical role in enhancing battlefield awareness.
Hot air balloons were used to spy on the enemy. They were also used to communicate, send supplies, and drop bombs.

Government balloons are just like normal balloons except for the fact that they are used for government purposes. The government will use hot air balloons to transport military supplies, carry weapons, and to travel.
When hot air balloons were first invented, they were mainly used for recreational purposes and entertainment. They were also used for scientific experiments, such as studying the atmosphere and meteorology. Additionally, military forces used hot air balloons for reconnaissance during wars.
Hot air balloons are now mostly used for leisure
if you have a helicopter or a military grade hoover craft Hot-air balloons and gliders can be used
It is simply air that has been heated. Hence the namehot air balloons are filled with hot air from a propane tank
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.
Helium is used to inflate balloons because it is lighter than air and that makes the balloon float.
