Looks like a real old article.
I'd rather see an experimental unit use this on several training operations... urban, desert, jungle, etc., put it through just about EVERY bad thing a soldier has to put up with and worse and see how it survives for at least a month and perhaps two without any kind of technical support and even a lack of battery re-supply.
And they'd have to whip the crap out of every other small unit type we have. The ultimate test would be to have a group of reservists with minimal infantry training to undergo a few weeks of familiarization training and them put them up against veteran infantry units.
If it can hack that, then I'll be sold.
