I did some calculations a while ago and I have a Theory that a Reaper thanix cannon can cleave right through a Covenant ship.

The only problem the Reapers have is the limitations of Element Zero tech, which is it only affects gravity and kinetic energy. That's a real problem when they meet people that use main weapon DEW.
