You know... there's a reason Green Lanterns have such a large section under Weaksauce Weakness.
You would think that a large miliarty-type organization, which knows it's superweapons have these giant flaws in them, would include training on how to overcome them? Or at the very least, encourage their troops to practice ways to get around it.
I mean... grab a chunk of wall and fire at the thing. Open up a spacial warp and drop the thing in the nearest star. Just grab the entire room and fly with it. Something! </rant>
