[expand]The light cavalry screened and scouted. The mounted archers advanced before heavy cavalry, engaged enemy, identified positions and weaknesses, and sometimes softened targets through preliminary harassment. The light cavalry’s information gathering informed heavy cavalry deployment—where enemy was weak, which formations were shaken, when opportunity existed for decisive charge. The coordination required trust and communication—light cavalry needed to screen without impeding heavy cavalry movement, heavy cavalry needed to exploit opportunities light cavalry identified.
The infantry provided support and anchored positions. Even among steppe peoples who were predominantly cavalry, some infantry existed—captured soldiers, allied contingents, occasionally tribal members unsuited for cavalry service. The infantry could hold defensive positions, provide rallying points if cavalry charges failed, and exploit breakthroughs infantry might traverse. The combined arms approach used each element’s strengths—cavalry for mobility and shock, infantry for holding ground and defensive resilience.
The reserve forces provided tactical flexibility. The committed forces that all-or-nothing charges were dangerous—if charge failed, no reserve existed for recovery or renewed attack. The wise commander retained reserve forces allowing response to unexpected enemy moves, exploitation of breakthrough opportunities, or covering retreat if main force was repulsed. The reserve management distinguished superior from merely competent commanders, the ability to commit reserves at decisive moment often determining battle outcome.
