2 Rax Academy

A bio timing attack that opens with two barracks and an early academy for medic production. The goal is to hit Protoss with a Marine/Medic push with stim pack research around the 7-minute mark, before storm tech is available. This is one of the most aggressive standard TvP openings.

Execution centers on constant marine production from both barracks while researching stim pack. Once you have roughly 8 marines and 2 medics, push across the map. Stim micro against dragoons is essential — pull back wounded marines, stim forward to close range. Keep producing reinforcements at home.

Best used on maps with short rush distances or when you scout a greedy Protoss opening like fast expansion without range upgrade. Transition by adding factories for siege tanks if the initial push does not kill. Weak against fast reaver drops that hit your mineral line during the push, and against dark templar if you lack scan energy.
