The Ru-20 Bodyguard is a unit of infantry soldiers in the Russian Army, and are referred to as "drones" due to their duties.
Instead of deploying sentry drones, the SGB uses Ru-20 "Bodyguard" Platoons for menial guard duties. Bodyguard units are not as well armed as their Spetsnaz counterparts, but do receive slightly more training than a typical Russian army soldier.
They are in the same formation as riflemen meaning there are 20 of them rather than 4 average drones you get with other command units. Along with that they can also utilize cover, meaning ever farther range, attack power, and defensive power than a combat drone. You can also see them as sentries, meaning they might need a lift from BTR-112 Cockroach APCs. Their main weakness, as with Force Recon infantry, is their lack of shielding, in which they are easy prey for anyone brave enough to fight.
Behind the ScenesEdit
It is unclear what "RU-20" stands for. For all purposes, these are conventionally-equipped human soldiers. The render above indicates they use AKMs, while wearing little body armor. Their helmets may or may not be modern kevlar ballistic helmets, but certainly lag behind special-forces grade hardware. They do not seem to wear armored vests, although they could, like Spetsnaz, wear them under their field fatigues.
