Camp Hammond has been taken as the Skrulls main HQ on Earth without the Initiative consent. Obviously, there will be retaliation and the Shadow Initiative will be the spearhead of the counterattack. But maybe the best weapon of these brave soldiers are nothing else that a coward, weaselly tiny man.

From Marvel.com:

Camp Hammond has been overrun, not just by the occupying Skrull army, but by the SKRULL QUEEN, herself! Well guess what? That's just what the SHADOW INITIATIVE wanted! Join MUTANT ZERO, TRAUMA, BENGAL, CONSTRICTOR, and ANT-MAN as they try this war's most dangerous mission: to take out the SKRULL-SPIDER-WOMAN! That IS why you stayed behind, right ANT-MAN? Also: As 3-D MAN and the KILL KREW carve a green, bloody swath across America, their numbers continue to grow. And in this issue, a classic AVENGER signs up-- and joins the AVENGERS: INITIATIVE ongoing cast!
