The Unimog (from the German "UNIversal-MOtor-Gerät", meaning "universal motor machine/equipment") is a series of trucks from Daimler-Benz designed shortly after WWII, originally to be used as slow-moving tractors for Germany's potato harvest.

They feature very high ground clearance ( greater than the Humvee ) made possible by portal gears that allow the axles and transmission to be higher than the tires' centers. Unimogs also feature a flexible frame that allows the tires a wide range of vertical movement to allow the truck to comfortably drive over extremely uneven terrain, even meter-high boulders.

A skipper is a man who has command of a boat or ship. It is more or less equivalent to "captain". At sea he has absolute command over his men. He may or may not be the owner of the boat.

The word is derived from the Dutch word schipper; schip is Dutch for "ship". In Dutch sch- is pronounced [s-kh-] (not [sh] as in German), and English-speakers rendered this as [sk-].

The word "skipper" is used more than "captain" for some types of craft, for example trawlers.

In U.S. Navy slang, it is a term used in reference to the Commanding officer of any Ship, Unit, Platoon, or Detachment regardless of rank. It is generally only applied to someone who has earned the speaker's respect.
