Ungh. Personally I believe most Btech designs are rather hit or miss; the Blood Asp and Shadow Cat showing two of my most common gripes. Why, oh why make the location of your cockpit so hideously prominent and vulnerable? The Vulture has a more sensible layout, and reduced field of view from things beneath...? Easily solved by a gun-camera. As for the Blood Asp; missiles. Things that explode. Right at the center torso. Where most people would normally aim at, as a matter of course. Granted, many other designs do this, but at least the Atlas puts the launchers at an angle, off to the sides, and we take it for granted that its primary saving grace is a monstrous amount of armor.
That said, the Uziel:
Protected cockpit, rounded armor, missile pod location less critical to the 'mech in case of blow-out... seriously, I'm surprised why this is said to be not so well-armored as it appears to be. The leg structure's a bit complex, but it's a very well-rounded mech suited for mass production.
edit:
Well, it IS a mass-production 'mech, after all. What's the hate-on for mass-production types in most mecha media? It's where you distill the most elements that make sense; THEN spam them at the enemy. Never are heroes all the most badass as when they do it in a mass-production or until then second-tier machine; proving it's the man that makes the mecha dangerous, not vice versa.
Not Wing's plot armor, though. That's just lame.
Amuro kicking ass in melee with a Guncannon? Awesome!
