This work starts and ends with the future of military gear. I think this is meant to draw in and keep the viewer who doesn't really care about the history of this gear.
This was informative. I learned that the mane-like attachment on Ancient Greek outfits served no practical purpose (not even for swatting flies?). The work tells why knight's armor rose and fell out of use.
It makes sense that canons aren't mentioned as they are not "gear." Still, as this work focused more on weapons than on clothing, it did seem like there was an absence. The work cites the French in World War I for making metal helmets. What about the pointy hats worn by Prussians in the century before? Even "The Simpsons" honored and mocked that.
The dove in me wonders how the hawks who would be lured to see this will respond. The models hired to recreate images could have been like those Civil War imitators: you could tell they love playing make-believe. One Roman soldier was seen with a full beard and I learned in history classes that Romans viewed beards are barbaric or uncivilized. Students who do creative anachronism may love this work too. Since I'm not a war enthusiast, I have fears about this being a tool for military recruitment. No matter how advanced military gear gets, let's hope that the numbers and extents of wars can decrease. I worry that not all viewers will agree with that, unfortunately.
