We need some GOOD Rebel soldiers now!
Just wait for it Jesse that Luke/Deana in stealth armor comic pack is coming out soon. 
That is what I expect in a soldier, not someone in some cargo pants, a multipocket vest, and a bucket for helmet. Not that it H's fault it's Lucas.
This guy will look good though prepping an xwing, still doesn't make sense why a mechanic needs to carry around a blaster. Seems like carrying an umbrella when it's not raining, you're just not going to use it for anything.
Well, not sure I'm totally into the Luke and Deena... It's an EU design and all, and it's not bad, but I'm just not sold on it totally yet. I've always rather liked the Alliance's uniforms... They're not the Empire obviously, and full body armor maybe just isn't feasible for them... They're putting together a cohesive uniform structure to represent them, but trying to do so at minimal cost too. Plus while the Alliance is small compared to the Empire, they're probably massive by "Earth standards" so clothing that many soldiers would be complex. I've always pictured them like our soldiers in the Revolution... You'd have some ragtag looking groups, some militias that didn't "conform", but you'd have the bulk made up of the continental regulars trying to look as uniform as possible.
The pockets all make sense... They're crews for ships as well as fighters, so they've got uniforms that work for both. Their helmets provide protection to the face, the neck, etc. Full body armor doesn't help the Empire too much either... It probably serves some benefit, but the Alliance maybe just doesn't see it as "worth the cost", at least not yet.
I've always envisioned the "Techs" as something more than just grease monkeys too... Mechanics in the U.S. Military still must pass basic small arms training to move onto their specialty. The Alliance, while large itself, is dwarfed by their opponent so I'd imagine every "able body" is expected to fight if the need calls for it...
Here's another real world example of this though. One of my best friends growing up, and someone I considered as close to me as a grandparent, was an old couple I delivered papers to and spent time with. They've both passed away but Mr. Wright used to tell me stories about his time in the war. He was an engineer in the U.S. military and didn't see much combat in Europe, but during the Battle of the Bulge in the Ardennes Forest, he and his men were in the midst of the fighting and the Engineers all had to fight with the regular infantry, airborne, etc.
He maybe built bridges, bases, airfields, etc., etc., but when the **** hit the fan he had to pick up an M1 with the rest of the men and fight.
I consider the Rebel Technicians as something similar... They're doing the laborous work to build the bases and things, but if (when, if you follow the EU) the Empire lays siege to the base, the base's personnel must all defend it. They're basically all soldiers to me, just some are specialists that work on ships, or fix fighters, etc.
I think a post-ROTJ Rebellion maybe has more stability to up-armor their troops, but really armor seems like a luxury in Star Wars. Even the Empire uses it on Stormtroopers only while other troops seemingly either get no armor, or very minimal (EU says chest plates like Veers wears are standard issue field gear for "Imperial Army Regulars", and one could maybe guess others get the same armor issued, but nobody wears the full set but a STormtrooper, who is ultimately "elite" on some level).
