RAMSTEIN, Germany ( TheStreet) -- A chilly early morning runway at Ramstein Air Force base in Germany feels a million miles away from the comfort of TheStreet's offices on Wall Street, but it's the first stop on my journey to witness a crucial part of the U.S. military in action. Over the coming days I will be swapping tickers and tech earnings for transport aircraft as I travel to Afghanistan to cover an Air Force Aeromedical Evacuation mission in action. The first stage of my journey, from Dover Air Force base in Delaware to Ramstein, was spent in the bowels of a huge Boeing ( BA) C-17 packed with military materiel. The seeds for this trip were sown on a blisteringly hot day at the USS Intrepid museum in New York last summer. As part of the city's Air Force Week, TheStreet was invited to check out some of the military's latest health care technology, from artificial lungs to virtual reality systems for treating PTSD. Much of the gear on display was designed specifically for Aeromedical Evacuation -- a highly sophisticated form of mobile medical care whereby aircraft such as the C-17 and the Lockheed Martin ( LMT) C-130 are turned into flying hospitals for wounded personnel. Pioneered in the aftermath of World War II, Aeromedical Evacuation, or AE, plays a critical role at the heart of the U.S. military. Since the start of Operation Iraqi Freedom on March 19, 2003, Air Force AE personnel have conducted nearly 200,000 patient movements and flown almost 42,000 sorties. Keen to explain the sheer scale of this operation and tell the stories of the people involved, TheStreet was invited to embed with the Air Force on an AE mission. This explains why I'm at the sprawling Ramstein Air Force Base in Southern Germany, en route to Afghanistan, where I will see the operation first hand. Embedding with the military, though, is no small undertaking -- I have even had to rent body armor and bring a helmet with me as a condition of my embed. Both items, as stipulated by media rules set by the International Security and Assistance Force in Afghanistan, have to be military grade. For the body armor, this means two heavy duty plates (one front and one back), which fit into a vest made of extremely thick blue nylon. (ISAF rules also insist on non-military colors, so no camouflage).
