While politicians and pundits make a lot of noise about getting the troops better body armor, the troops are asking for less, or at least lighter and less bulky, armor. Anyone who has been in combat will tell you that survival depends, first of all, on speed and mobility. Body armor helps when you do get hit, but the latest body armor often slows troops down and makes them vulnerable to hits in unarmored areas (the face, and limbs). Troops traveling in vehicles find the body armor a major obstacle to getting out quickly. This can be a matter of life and death. Another problem is fatigue and heat. The heavy armor is cumbersome, and wearing it in action wears you out more quickly.
No one, except the troops who wear the stuff, appear to realize how critical weight and bulk is.
