## Description of the bug
The bug is that the comtech's BRUTE is able to aim and fire at deployed stasis bags. (This can also round-remove marines if the comtech does shoot)

## What's the difference with what should have happened?
You're unable to target stasis bags with brute because TECHNICALLY they aren't structures.

## How do we reproduce this bug?
1) Get a BRUTE launcher.
1.5) Get a stasis bag.
2) Deploy stasis bag.
3) Two-arm brute and target the stasis bag.
4) Fire away and the bag is a "structuure" because the game said so or something.
Results:
Direction removed of walls including the stasis bag.

If there's a marine/mob inside the bag:
Marine/mob inside the stasis bag gets round-removed via deletion of the bag while they are inside of it.
