Actually, every force needs to secure captured territory.
Less to sweap over it finding last pockets of resistance, but to understand new supply line routes, supply hubs, built field hospitals, find new commando positions and bunkers, build and restore bridges, shelters, crate wired or direct communication lines, position small radar bases and draw lines of defence if a retreat was needed.
Modern large unit warfare is due to weapons of mass destruction way more complex than to Napoleon's times and even by improved communication and information processing than during WW2.
Today, a General can lay out after having taken down a frontline position to force the enemy into retreat several miles away an entire net like carpet of different small unites from quickly digged in forward LMG and heavy Sniper nest positions, mine field placing units to limit enemy counter attacks, pocket hubs for of Frontline Soldiers in attack units bypassing the Nests to face enemy positions, mobile radar and telecom positions, Anti-Aircraft manpad positions, light armoured to armoured personal carrier shelters and forward Artillery positions of Mortars and Howitzers all controlled from a mobile computer network tent Field HQ.
Atleast theoreticaly considering the available tec.
