That looks really impressive to "me" at least, but I'm not exactly an expert. Can someone with some solid knowledge on armor say if this is significant? That Troy's soft armor is definitely a lot better than the a particular make of NIJ II tested kevlar armor ...
Don't be so easily sold on this, and in particular don't let this little video convince you that Hurtubise's product is right for the military.
1. He makes claims to the effect that the depth of displacement of the first two shots are immeasurably insignificant. However. the fact that he does not measure after each shot means that we cannot actually know the displacement caused by the first two shots. Note that at the end of the test the surface is shaved in order to remove material which was bulged forward due to the displacement of the armour into the clay during impact. This same displacement of clay will make the depth of penetration of previous shots appear shallower as consecutive shots land near & displace clay. While his display looks good, it does not demonstrate if his product will or will not meet NIJ II standard. If he wants to prove that he meets or exceeds the standard, he should test his product according to the standard.
2. While Mr Hurtubise reiterates that his product is as light & less expensive, he does not discuss flexibility. In the brief side by side comparison, his product appears somewhat stiffer. Coincidentally, the CF recently (~'05/06) changed its soft armour because soldiers in Afghanistan complained it was too stiff & restricting. Armour needs to be flexible enough so that the wearer can perform his duties. Mr Hurtubise has not demonstrated this.
3. The video title claims this a comparision between Mr Hurtubise's soft armour and "all soft armour." This is deceptive. Even if his intent were to prove his armour is superior to all NIJ standard soft armours, the title fails to bring out that there are higher protection standards in NIJ than level 2.
4. Using NIJ to demonstrate a product's suitability as a military soft armour is an all around bad idea. NIJ is a police standard & as one progresses up the levels of protection they will be earning themselves protection against the better pistol bullet. NIJ makes no account for protection from frag, and a funny thing about frag (despite Mr Hurtubise dismissing it in one of his earlier videos) is that it can have much higher cross-sectional kinetic energy densities when compared to small arms. Frag can shred soft armours designed to protect against bullets. In the military, unless one believes that the better pistol bullet is a bigger combat danger than frag, then accepting only NIJ standard in a soft armour is a gamble with one's life. A higher NIJ number does not guarantee better frag protection either. As it is not considered in the development of NIJ armours, frag protection may not be designed for nor tested for (and likely neither). In some cases, NIJ armours of a higher protection level actually will provide reduced frag protection. This is one of the reasons that the CF does not use NIJ as a standard for its armour. If Mr Hurtubise wants to sell his soft armour to the military, he'd better prove it against frag.
