Captain our teams are overworked and can't keep up.

Well, then tell them to work harder!

But our tanks are breaking down!

Then leave them behind we have no use keeping people who can't keep up. if they fall into the river abandon them.

Our teams need a break! Captain, please!

Well, then I have no use for you either. off the team! and all who can't make it to the other side of this mountain range by nightfall is off as well!

But that mountain range is at least 100km wide and the smallest one is 6000meters tall! why
