Infantry Armor

From The StarCraft 2 Wiki

Infantry Armor is an upgrade that is available for the Terrans that enhances the armor rating of all infantry units. Each upgrade is accumulative and automatically adds to the base armor of all units that are built from the Barracks.

[edit] Costs

The research time for each armor upgrade has been reduced considerably since StarCraft I.

Upgrade Level	Mineral Cost	Gas Cost	Research Time
Level 1	100	100	140
Level 2	175	175	170
Level 3	250	250	200

[edit] Affected Units

The Terrans in StarCraft II have four active units, and two canceled units, that are constructed from the Barracks, as well as the SCV from the Command Center:

StarCraft II Unit	Armor Bonus *
SCV	+1
Marine	+1
Marauder	+1
Ghost	+1
Reaper	+1
Medic **	+1
Firebat **	?? ***

* The armor bonus is accumulative per each upgrade level.
** The Medic and Firebat have been removed from the open multiplayer aspect of the game.
*** Since the Firebat was briefly moved from the Barracks to the Factory before being dropped it is unsure whether Infantry Armor or Vehicle Plating will apply.
