KitUp has an interesting take on 9/11: how the post-attack war on terror have affected US soldiers. On the right there's a typical infantry man taken on September 10, 2001. On the left, a soldier with today's standard equipment.
The former is wearing a really heavy Kevlar helmet, a very basic and ineffective armour vest, Vietnam-era gear, a standard M4 gun -- if he's lucky -- with no aiming aids whatsoever. The latter is using a lightweight helmet, a rifle with laser and IR aims, high end mountaineering boots, and armour plates all around his light-weight fire resistant combat shirt -- everything configurable depending on the needs of the mission.
As Christian puts it, the Vietnam soldiers have turned into Starship Troopers warriors. [KitUp]
