Actually the reason they missed every shot when they were shooting at the main characters in the Death Star is because they were explicitly told not to hit the main characters in the Death Star, as Leia immediately points out when they escape the Death Star without immediately being shot down by like a million space fighters. Which we later see verified when the Empire follows them from the Death Star to Yavin IV with a tracking device
And don't even bring up the ewoks. Remember that time the US lost the Vietnam war? Sometimes vastly superior technology and training isn't a match for home turf advantage. If you're gonna criticize the Empire for their tactical blunder there, criticize them for not bringing a Star Destroyer and destroying the whole forest from orbit.
The US won every major engagement in Vietnam though,and usually by fairly significant margins too. For the analogy to work, the Empire should have massacred the ewoks, only for Palpatine to get voted out and the new emperor to withdraw.
Those were standard military engagements, as in two armies facing off against each other with clear strategic goals. The US had the greatest military force in the world at the time, so obviously they would win in a straight up fight. Where the US military struggled was with insurgency, and they struggled with it again in Afghanistan. When the force you are fighting is able to disappear into the forest, a lot of your advantages get neutralized. You can't drive your tanks through the forest, for example. The ewoks obviously don't work as a 1 to 1 comparison, but fit pretty well with popular perception of the Vietnam war.
Yes, this helmet is too small for the head, also keep in mind that the helmets are worn with a slight tilt forward and everything below the mouth grill goes below the chin. See these pics for an idea of scale from the black series helmet.
I never understood this design "development". Clone trooper helmets provided a far superior field of view, especially the later ones that look like an intermittent stage. Why would seeing less be an advancement? I can agree on whatever other technological improvements the new ones bring, but they would still be better spent by going into an old style helmet
Ultimately I know of course it’s the rule of cool, but still.
I have always assumed they were looking at a washed out, faded display screen that kind of flickered occasionally and showed them a view of the surrounding area but not necessarily what they were looking at.
I've always assumed that those aren't eye holes. It would make sense for them to have a display screen that displays their view, overlayed with tactical information and a targeting reticule. But given their aim, I think you're right and they're just eye holes with sunglasses material over them.
