Wakina + Bow Rider VS Swiss Pike

I learned tonight that an army of only swiss pike can wreck a larger army of Wakina, Bow Rider, and Rifle Riders. Their unit description should just read "kills Lakota". I bet you are wondering by now, "well why didn't you just kite them with rifle riders"? Because he was just sending 5 randomly all over the map in cover mode making it impossible to escape, while 4 of them just take down my TC with ease. I though 20+ rifle riders would do the trick but I was wrong. I'm dead inside.
