One of their light walkers carried a weapon of lethal effect. It fired a form of ultra-high velocity projectile. I saw one our tanks after having been hit by it. There was a small hole punched in either flank — one the projectile's entry point, the other its exit. The tiny munition had passed through the vehicle with such speed that everything within the hull not welded down had been sucked out the exit hole, including the crew. We never identified their bodies, for all that remained of them was a red stain upon the ground, extending some twenty metres from the wreck.

"That MAC gun can put a round clean through a Covenant capital ship. With coordinated fire from the Athens and the Malta, nothin's gettin' through this battle cluster in one piece".

"This, Recruits, is a 20-kilo ferrous slug. Feel the weight! Every five seconds, the main gun on an Everest-class dreadnaught accelerates one to one-point-three percent of light speed. It impacts with the force of a 38-kiloton bomb. That is three times the yield of the city-buster dropped on Hiroshima back on Earth. That means: Sir Isaac Newton is the deadliest son-of-a-bitch in space!"
