Can someone explain the suicide rush to me?

Lert: Here's your explanation:   Wheeeee I skouwt reel gude for teem! \o/     Arty y u no kill red teem i lite up reel gude! u suxx uninstall!   What they forget is that we don't need to know where the enemy team is at battle start. We already know: at their spawn. We need to know where they are 5 minutes into the game.
