Siege Expand

[e][h]Siege Contain > Expand

Strategy Information

Matchups:

TvT, TvP, TvZ

Type:

Economic, Rush, Contain

Overview

The fire-power of early Siege Tanks and mass Marines has map control and can easily setup a contain at the opposing army's main ramp. It can even outright kill plenty of tech builds before the tech finishes and becomes a threat, for example Dark Shrine and Banshee openings.

Usually, this is started after a Reactor Hellion Expand (vs. Zerg). You then get a strong army to defend counter rushes that Hellion opening strongly encourage.

Goal

Start massing Siege Tanks early, with Marines for support and punish any fast tech or expansion build and contain the opposing natural and expand. It is more of a ladder build that prepares for a contain to negate cheese and punish early expand builds.

Basic Build Order

Economic Expand-Friendly Build
10 - Supply Depot 12 - Barracks 13 - Refinery (1) 15 - Orbital Command 15 - Marine (1) 16 - Supply Depot 18 - Factory 20 - Refinery (2) 23 - Supply Depot 24 - Reactor on Barracks, Tech Lab on Factory 25 - Siege Tank 28 - Supply Depot 29 - Marines (5) (6) 31 - Siege Tech

Note

• Siege Tech timing is 6:30 but aim to start around 5:00-5:30.
• Expand after Siege containing the opposing player's natural.

Execution

• Use early Marines to hold the Xel'naga Towers before/until pushing out.

Adaption

• Off of a Gasless Expand, quickly get both Refineries. At 100 gas, build a Factory.
• Important feature is the ability to switch into a Reactor Hellion build, but this does not work well as an opening outside of TvZ. So, it is best to complete Stimpack or a Starport or Siege Tech to defend Roach Rushes, etc.
