A Russian mercenary group listed equipment failings that troops are suffering on the front line.
The group, known as Rusich, said soldiers were buying their own communications equipment.
The report didn't specify what kinds of communications technology Russian troops were buying, but there have long been reports that Russian soldiers lack the equipment to communicate effectively and so use cell phones or their own radio systems.
"High-precision ammunition, communications equipment, drones etc... We have them, but unfortunately, there is not enough."
The problem has persisted despite a ban last year on Russian forces using cell phones on the front line.
