During World War II Medaris was a colonel in the ordnance corps of the First Army, participating in the North Africa campaign, the Allied invasion of Sicily, Normandy landings, the Battle of the Bulge, and the invasion of Germany.

Two wires, and two trolley poles, are required to complete the electrical circuit. This differs from a tram or streetcar, which normally uses the track as the return path, needing only one wire and one pole (or pantograph). They are also distinct from other kinds of electric buses, which usually rely on batteries. Power is most commonly supplied as 600-volt direct current, but there are exceptions. Currently, around 300 trolleybus systems are in operation, in cities and towns in 4 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Army Reserves
A military reserve force is a military organization whose members have military and civilian occupations. They are not normally kept under arms, and their main role is to be available when their military requires additional manpower. Reserve forces are generally considered part of a permanent standing body of armed forces, and allow a nation to reduce its peacetime military expenditures and maintain a force prepared for war. In countries with a volunteer military, such as Canada, Spain, the United States and the United Kingdom, reserve forces are civilians who maintain military skills by training periodically (typically one weekend per month). They may do so as individuals or as members of standing reserve regiments—for example, the UK's Army Reserve. A militia, home guard, state guard or state military may constitute part of a military reserve force, such as the United States National Guard and the Norwegian, Swedish and Danish Home Guard. In some countries (including Colomb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
