I disagree. The Ukrainian offensive operations in Kupyansk and Zaporizhzhia from last fall and this winter demonstrated that offensive maneuver is possible even with brigades and regiments that only had a company-size element of infantry. In both cases, breakthroughs were possible if Ukraine had sufficient forces to exploit success. Proper planning, task organization, rehearsals, intelligence, and employment of fires/CUAS can set the conditions for successful offensive operations. UAS can enable, not only hinder, maneuver.

Due to scientific and technological progress, it has become impossible, regardless of what others may claim, to carry out operational-level tasks. 1/12
