New extremely effective reaper opening

[{Thisson}]

On some maps it's really hard to deal with a fast rush. On War garden, for example, if P1 spawns a soldier and advances it towards your base along with their heavy, it's very difficult to repel the attack because as P2 you are behind on tempo and as a practical matter you need to have an extra unit to take out a buffed heavy. Some of these map starting positions seem to overly favor a rush by player 1.

Here's an example. I made a small mistake moving my medic but even if I hadn't I don't see any way I could have repelled this rush. Does anyone know how to defend against this rush as p2?
