They did not have paramedics, no one was trained in field surgery. That's the difference between a paramedic and other first responders. That innovation came during Vietnam. Source, the US Department of the Army film, Combat Medicine in Vietnam.

Bushnell's Turtle, Revolutionary War. Paramedic: maybe definition changed, a doctor here in the early 60s told me he was a paramedic & jumped on D-Day.

If it wasn't for warfare we wouldn't have the wonderful recreation that is called ballooning.

Probably the first example of balloons being used in warfare date to 2-3rd Century China (Kongming Lantern) and invented by Zhuge Liang.

They got a good look in in the US Civil War and the Russo-Japanese War (1904-5), especially the Battle of Liaoyang.
