A way to enter/get to the random weaponizer in Norway?

Googled, youtube'd and can't seem to find a way to get to the random weaponizer that the 6 heavily armed gaurds are by - 2 per gate.... is this meant to be inaccessible?
Seems like it should be... as every level had a random weaponizer... so far, until this one.
I appreciate any tips or answers.
