[2019] new specialization: OPTICAL CAMOUFLAGE

I'd love to see a new non-weapon based specialization, something like the OPTICAL CAMO from GHOST RECON WILDLANDS: https://youtu.be/lohrgEPDEK0?t=227

it would be a nice way to get around between cover, infiltrate, or break contact if overwhelmed. obviously it would need to be balanced (battery based, with "ammo' drops as "batteries", or a long cooldown, etc.). Maybe not proof against thermal, IR, or PULSE? Maybe have the cloak break on any aggressive action (shooting/melee or running)?
