Massive Air Drop
A devastating strategy if not defended against is the air drop. Take a Dropship full of 8 Firebats
or Marines and sneak around enemy defenses to drop them in the middle of the enemy town (usually
right in the middle of the ). If the enemy does not have any air defenses, your Dropships
can unload with ease. But if the enemy has some anti-air defenses, this strategy doesn't work as well because
of the slow unload rate for Dropships. For a relatively cheap price, you can hoard a fleet of Dropships filled
with Firebats and Marines. Sneak the Dropships around the map, trying to avoid detection, and
find a landing spot where the Dropships can unload without being attacked. Stim Pack the Firebats and
Marines. This strategy is best done by unloading in the resource operations of the town as it is most
confusing and damaging to the enemy.
The key to defending against this strategy is fairly simple. For Terrans, place Bunkers and a few Missile
Turrets around the resources and town. Protoss players should place Photon Cannons around the resources, or use
groups of Dragoons. Later on they can use air units such as Carriers and Scouts for defense.
Spore Colonies are the best anti-drop defense for Zerg.
They provide cloak detection, have a pretty long range, and do considerable damage to
Dropships (or other transports). If the enemy is able to land Dropships without being attacked, they will easily be able to
destroy a town fairly quickly. Expansion towns are especially vulnerable to this type of attack. This strategy
is also something to watch out from the Protoss and Zerg Races. Protoss players can unload 4 Zealots per Dropship
or 2 Reavers while Zerg players can place 8 Zerglings in an Overlord or use 4 Hydralisks.
Million Man Marine March
This strategy involves producing a large amount of un-upgraded Marines. Build a Supply
Depot at about 8 to 9/10 supply. Continue making more SCVs, and build a Barracks. Build
another Depot, and a second Barracks. Continue making more SCVs, Supply Depots, and build another
two Barracks to bring the total to four. Start building Marines, but be sure to evenly distribute the Marines
across all four Barracks. For example, build 1 in the first one, 1 in the second, and so on.
The idea is to have all four Barracks building constantly. To make this easier,
assign the Barracks to control groups 1-4. Make sure you Rally all four Barracks to the same location,
usually near your SCVs mining Minerals to protect them. Once you've assembled a large
group of Marines, you can charge the enemy. This should work very well vs Zergling rushers,
Hydralisks, and Zealots. Build a Refinery, Academy, and Engineering Bay to research Stim Pack, U-238 Shells for added range, and upgrade your
Marines to add to their advantage. Stim Packs are the most essential upgrade, as it doubles the effectiveness of
your Marines. Add in Medics as soon as possible for an even better combo.
Your best bet is a lot of Hydralisks from at least two Hatcheries. Make sure you research
Grooved Spines in the Hydralisk Den to give your Hydralisks a greater range. If the enemy
insists on continuing to build nothing but Marines, build Queens and cast Ensnare on the Marines.
This should allow you to overpower them without taking severe losses. Then build Guardians which should be able to fire
on the Marines at greater range, killing them easily and quickly in numbers.
A nice thick defense of Bunkers filled with Marines should allow you to defend your town until you
can make Siege Tanks or build lots of
Vultures, which are very effective in countering large amounts of Marines. Research the Spider Mine upgrade
and start laying Mines also. Be sure to repair your Bunkers, Tanks, and Vultures to keep them in full form.
Build 3-4 Gateways and a lot of Zealots. You can use multiple Shield Batteries to extend the life of
your Zealots. If the enemy continues with this strategy, quickly build Reavers with the Increased Reaver
Capacity upgrade. You can kill as many as 8 Marines with one Scarab if you are lucky, and a pair of Reavers
can wipe out huge groups of Marines. Archons also work very well against Marines. While you are building
Zealots, you often save up a lot of gas. Use this gas on Templars. Cast Psionic Storm
on groups of Marines, then use Templars with no mana remaining to make Archons which will quickly
work through the large groups of Marines.
