I believe there is 15mm+ HDPE behind? And multiple bulkheads back and forth. The armour panels will likely get pretty torn up but the underlying structure should last well. If you don't mind me posting, Chris: https://scontent-b-ams.xx.fbcdn.net/...54003891_o.jpg

Chunky!

Also, 8mm HDPE is a little lighter than 3mm alu, and in certain situations would likely hold up a lot better. It'll get mashed and gashed but it'll do a good job of protecting if mounted well. The counter intuitive thing with thin metals in full combat is that they're actually less suitable than less dense (but thicker) material. 3mm alu (or even 3mm steel in truth) will bend and be pierced and stay that way, whereas something like 8mm HDPE will just bounce back, so it lasts longer.

Either way, this is a brilliant step up from the first incarnation of Loki. Look forward to seeing it.
