Which consequence results when Roman legionaries insufficiently tamp rammed earth layers behind a siege rampart?

💡 Explanation

When soil layers are poorly compacted, consolidation settlement occurs because void spaces within the material reduce under uneven stress from the heavy siege tower, causing differential settlement. Therefore rampart buckling will occur, potentially endangering the tower crew, rather than creating vulnerabilities to projectiles or subterranean attacks, or generating tool failures.
