When it comes to military and humanitarian operations, obtaining a steady, reliable source of power is of paramount importance and this has only increased over time. As a result, the world's major military forces invest a staggering portion of their budgets to supply electricity, fuel, power plants, and all that goes with them as part of an increasingly complex supply line.

However, no matter how much power technology improves, there's still the ever-present problem of getting that power from Point A to Point B – a problem that is often insurmountable across the infamous last mile where power lines cannot be slung or pipelines buried and soldiers are often reduced to hauling jerry cans of fuel over rough country by hand and back muscle.
