Very fast

Iapetos wasn’t bothering to spend his shells. His broad-headed sea-lance was enough as he methodically and brutally mopped up the trenchworks. He drove it forward now, in a perfect fleche along the top of a trench, shattering the pintle-mounted lascannon with enough reach left over for the tip to go a hand’s length into the belly of the frantic gunner. Iapetos dragged the lance back as the woman doubled soundlessly over, the quarter-turn of his body positioning him perfectly for a backhanded swing. The gun’s other crewman was halfway through throwing a grenade at a spot half a dozen metres away where Iapetos had been two strides and less than a second ago.
