An idiom referring to anything in your environment that can be used for defense.

Comments:

This typically refers to physical items that are not traditionally used for defensive purposes, but this is not a requirement.

An Environmental Defense can be non-physical.

Some Environmental Defenses that are often overlooked include (but are not limited to):

door

chair

car

person

speech

Environmental Weapon

Technically speaking a standard block or cover would qualify as an Environmental Defense, even though it would most likely not be referred to as such.

This term is closely associated with blockade.
