Because size matters, at times.

A 5-ton truck from the 212th Mobile Army Surgical Hospital in Miesau, Germany, rolls into the belly of a Russian AN-124 Condor (Ruslan) cargo aircraft at Ramstein Air Base, Germany, on Oct. 17. The truck is being transported as part of the disaster-relief response to the Oct. 8 earthquake in Pakistan. It's pulling a trailer fitted with a mobile, self-contained, two-table operating room that will be used in the relief effort.
