[6] Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3. It has the same crystal structure as corundum ...
Utilizing a breaching tool is unnecessary if the door is unlocked and easy to open. [5] [3] [6] [1] If the door is locked, breachers can attempt to force inward-opening doors with a strong kick. The breacher will aim to hit the door near the locking mechanism, but not kick the doorknob itself as one can easily twist an ankle doing so. [7]
