SAS and SBS missions differ from the work expected of conventional formations. Small specialist teams plan and execute high-risk, high-payoff objectives, but lack the numbers required for persistent patrols and holding ground. Assigning them those tasks wastes their specialist role and leaves the larger force's manpower needs unmet. A later example of Ranger units in Italy illustrates the danger of overusing elite infantry when ordinary line strength is insufficient.

Why special forces cannot replace line units
Elite units excel at narrow high-risk missions but lack the mass to patrol, hold ground, or perform a battalion's routine tasks.
