Six-wheel drive (6WD or 6×6) is an all-wheel drive drivetrain configuration of three axles with at least two wheels on each axle capable of being driven simultaneously by the vehicle's engine. Unlike four-wheel drive drivetrains, the configuration is largely confined to heavy-duty off-road and military vehicles, such as all-terrain vehicles, armored vehicles, and prime movers.
When such a vehicle only has six wheels by definition all are driven. When it has ten – with two pairs of ganged "dual" wheels on each rear axle as on a GMC CCKW – all are also driven but the 6×6 designation remains. For most military applications where traction/mobility are considered more important than payload capability, single wheels on each axle (often referred to as super singles) are the norm.
Heavy hauler and ballast tractor 6×6s have had a long history as prime movers both in the military (as tank transports and artillery tractors), and commercially in logging and heavy equipment hauling both on- and off-road.
Turn your eyes to me
I am watching every move you make
What should I wear today on my sleeve?
And let's take a step and move away
Underground is where we'll stay for a while
And I will mix my tongue with strings and drums
And give my soul away
Can you hear them come?
Strings and drums
And you're my mystery
You are always at my fingertips
Without you, I'm just bones and skin
And I will lick your cuts and be your bruise
Until I fade from deepest blue into white
And I will mix my tongue with strings and drums
And give my soul away
Can you hear them come?
Strings and drums
And I will change my words from nouns to verbs
And never be ashamed
Can you hear them come?
Strings and drums
And I am writing myself clean
And I am selling myself cheap
And I am aching for a touch or a taste
And I'm aching, aching, aching now
I'm holding, holding, holding out
I'm calling, calling, calling out to you
And I will mix my tongue with strings and drums
And give my soul away
Can you hear them come?
Strings and drums
And I will mix my tongue with strings and drums
And give my soul away
Can you hear them come?
Strings and drums
And I will change my words from nouns to verbs
And never be ashamed
Can you hear them come?
Strings and drums.
