When the scupts first came out, many moons and first edition ago, they were going for an NFL theme-the idea was to tie Capitol with American Sports (which is why the heavy infantry figs had football helmets). At the time I hated the Airborne Ranger helmets. Looking at them now, the fit in well with the asthetic that came with the 2nd ed sculpts and I have come to not mind them as much. As for being light wight-take a good look at your average US Army tab-wearing, plane jumping Ranger* and you will see that this isn't much of an exaggeration; those boys are beefy. The parachute drops you about the same speed no matter what you weigh (within limits).
As for a certain bear, Stephen Colbert said it best; "Just think of the person he had to maul to get that hat"
*As a Marine, it hurts me to say this, but it's for the good of the forum.
