Which defensive outcome results from the Roman 'agger' siege ramp?

💡 Explanation

Reduced projectile kinetic energy occurs because earth's density causes projectile deceleration via drag, minimizing arrow/stone damage; therefore defenders survive, rather than collapsing defenses; different topography prevents ramp utilization so impact angles vary
