Also, this is a raid not a siege. The plan is to get in, kill a known military target, and get out. Hakoda knows what he's doing, he knows that if he lets his men run rough-shod all over the place getting bogged down in engagements he'll lose.

Does that mean there will be zero civilian causalities? Unfortunately that's not very likely since urban warfare is messy business, but if he can keep the ratio of civilian to military causalities one-to-one or better he'll be outdoing most modern operations in that regard.
