Nanoswarm hive

"Use this to protect your forces from the Proton Collider!"
 * Suki

Recent intel surveillance has revealed one of the Empire of the Rising Sun's Superweapons: the Nanoswarm Hive, when activated, forms an entire hive of nanomachines that provide a large impenetrable shield around the target area. Structural integrity can only be maintained for aproximately 30 seconds before the nanomachines disperse. The Hive is, basically and in essence, a defensive Superweapon, much like the Soviet Iron Curtain.
