Right now a soldier on patrol [Now as in right now on the streets of Bagjdad there is a guy doing this literally almost] is carrying flak jacket, comm gear, first aid kit, knife, batteries for comm gear, helmet, goggles, water, chow, likely as not if he is US then some other fancy electronics crap plus padding and the normal accoutrements of clothing. All of this weighs just what the body armor in this system would weigh. Even granted that it replaces the flak/helmet combo this suit is still adding something on the order of 7-8 kg to the load a soldier is already carrying along with some SEVERE penalties in terms of freedom of movement. Now here is the problem, soldiers HAVE to RUN, they often have to sprint because their lives depend on going from cover to cover quickly. Any runner will tell you that every ounce you add to your weight is a penalty you will pay in terms of accelerating AND decelerating.
I didn't try to say someone wearing this won't be noticably slower in a dead sprint, or won't have a lessened degree of movement. I tried to say that 40 lbs is not as impossibly heavy as perhaps it might seem at first.
All of this is great...if you are standing still. When you are moving you have to exert the additional force neccessarry to move the additional mass and doing so in 120-130 degrees F makes such penalties very very real. Yes at rest and in a decent environment a well designed suit will not adversely affect the wearer but soldiers are in crappy environments where they are on the move for hours on end, the extra weight WILL make a difference
Then we agree about the movement penalties being small in a temperate environment, good
As I tried to convey with my post scripts I am very interested in the "Fresh Air" system. If it does not work well then this suit is clearly not up to deployment in Iraq however effective it may be in every other way.
Yes but they don't do cartwheels after walking and running about in 120F weather for 4 hours. The fatigue problems are not something which will be apparent over short term or mild climate use.
Of course fatigue builds with time and progresses faster in hot weather. I am of the opinion that as advertised (which is possibly distinct from reality) the suit offers enough movement and protection to warrent consideration of serious use.
IF the cooling system isn't good enough the suit fails in Iraq. IF the peripheral vision is hampered significantly the suit fails everywhere. It's mass however is not IMO a serious offense, considering its massive (repeat:
massive) defensive powers (as advertised).
