However, aluminum or steel carabiners do not belong on your tactical gear! A common mistake, by all trades within the military and in LEO tactical teams, is using a metal carabiner to clip a weapon or gear to a fighting rig. This is extremely dangerous. In a blast, these metal ‘biners become missiles and shrapnel helping the enemy inflict casualties. Milspec or climbing strength ’biners are strong; they have to be for their real job. This means should you hooked in a burning or overturned vehicle by that carabiner you will be unable to break free!! Should you have the presence of mind to carry an accessible knife, you cut yourself free, if you haven’t succumbed to the acrid fumes of the burning chemical smoke. Additionally, you are increasing your IR signature as climbing equipment is not traditionally IRR compliant. Noise is a factor; the sound of a ‘biner clipping shut is very distinctive and carries over the night air.
Take care out there.
All of the polymer/plastic 'gear clips' together weigh less than the carabiner
Additionally, their combined 'breaking strength' is a fraction of the same carabiner.
