Heavy Object

[Kraco]

The concept here is that it doesn't matter that you can see it or shoot it from miles away. They can detect you from miles away and kill you first, or they can just ignore you because of their armor.
Or they can just shoot down any projectiles with lasers.

Long-range planes and missiles are almost completely useless.

I wish you had even read my post before replying to it.

There's no reason to assume that blob has some supernatural sensors as impervious to damage as it otherwise seems to be. Does it has superman superzoom cameras that see through the armor or something? No, I don't think so. It only sees stuff from its limited viewpoint and relies on the single operator to react to the information gathered. Also, it has no way of hiding itself, unlike a smarter opponent. I also said, which you ignored, that since an object can destroy another object, there obviously are weapons that can destroy objects, the weapons we see installed on the objects. They are much smaller than the object itself. Take one of those weapons, install it on a platform of an actually usable size, and you can move and hide it at your leisure. Distract the enemy object from beyond the horizon or with mines and such, and while it's distracted, destroy it with the previously hidden weapon. Very cheap and very efficient.

Unlike the beginning of the episode would have you believe, modern warfare isn't the same as 200 hundred years ago: The heavy weaponry doesn't assume you must be within a line of sight of the target. When you attack something with fighters and bombers, you don't fly right next to the target. The same goes for ships.
