hmmwv door vent

[rlwheels]

What's the vent on this door for?

It's a type of applique armor. I believe the design is intended to fragment the projectiles and dissipate their force.

They are IR reflective panels, you are looking at the OFF side. When they are flipped over, they allow friendly aircraft to and armor to see the vehicle, and not blow it up.

 

[Elwenil]

Ha! Appears I have been misinformed. I always thought that explaination left a little to be desired since all of those panels are the same size and there is only one per side instead of the whole vehicle being covered. Learn somethign new everyday...

They are only sheet metal or aluminum. Look at the hood, there is on it also.

There is another shape/size that attaches to the tail gate with brackets, but all others that I have seen are the square shape and size.

It's not IR reflective, it's Thermal.. And if you look closely at one firsthand, you'll see that there is the thermal tape thats on the aluminum...

 

[Armymann]

I stand corrected, it is thermal tape, had a brain fart there
