This is probably a remote border security post. Removing these blinds russian boarder security and causes them to have to spend manpower to replace the unit, and until they do, manned recon is needed to prevent Ukrainian boarder raids in that area.

This is tactically important. A small attack increases the work load for boarder guards... during a war. These attacks require a much more intensive response to repair than their cost. And while the systems are down, Ukraine can attack outposts, and sneak in agents, through that part of russia.
