Hmg buildable? (Heavy machine gun)

As the title states;.

I was very surprised to not see any HMG buildings available.

This seems like a no brainer considering the other emplacements that have been added.

It would be nice to have like a tripoded .50 in the standing that rotates 360 like in squad. As well as .50 bunkers or even LMG emplacements even.

This could offer a cheaper option to defend against air attacks comparatively to the cram and or thrasher missile which is sure to get a nerf of some sort as it is extremely powerful right now, had a lot of fun on it during the beta.

Thoughts?
