NEW: Ukrainian forces encircle Russian soldiers at Lyman

The systematic constriction of exposed tactical salients—exemplified by Ukrainian interdiction operations northwest of Lyman—illustrates how ground lines of communication (GLOCs) dictate front-line sustainability across the theater. By applying convergent pressure against vulnerable logistical bottlenecks rather than assaulting fortified forward positions directly, interdiction forces impose disproportionate resource attrition on overextended elements. This operational geometry exploits rigid command doctrine, wherein the continuous reinforcement of deep pocket positions paradoxically accelerates vulnerability as flank security degrades. Consequently, the defending force faces a compounding operational dilemma between committing scarce reserves to stabilize contested flanks or executing costly retrograde maneuvers under fire. Over time, the systematic elimination of such overextended bulges shortens frontline frontage, optimizes force economy, and structurally shifts the theater-level initiative.
