They likely primarily act as a signal relay for other drones. We've seen some videos of FPS drones attacking artillery and ammo storage. These are likely many miles behind the enemy lines. Well out of line-of-sight for a ground based platform.

Firing middle managers is a fun way to kill the company. Not that cleaning house is a bad idea. Unfortunately the people making decisions of who to keep and who to let go are usually idiots.
Middle Managers are promoted for two reasons: technical expertise and ass-kissing expertise. Now the technical experts tend to not mix well with incompetent parasitic c-suite types idiots. The ass-kissers are beloved by the c-suite as that is their only role in life.
So when firings come around guess who they get rid of? Then 1-3 years later everyone is shocked when everything starts to fall apart.
