Infantry units are the most basic form of soldiers you control. The infantry units carry Machine guns and can fire on other ground units. Air units can fire on infantry units but they cannot fire on Air units. The units have 10 HP.
A stronger form of the Infantry unit is the Mech, which stands for Mechanized Infantry.
Infantry cost 1000G to produce and have a movement range of 3 spaces. The Orange Star CO Sami specializes in using Infantry and Mech units. Infantry get a sight bonus when atop a mountain in Fog of War maps, adding +3 to their vision range.

Since Infantry are cheap, you can produce a great number of them with enough bases. This means that creating a giant number of Infantry is useful for walling up a spot. A unit may only destroy one unit a turn, so a high amount of Infantry will take a long time to eliminate.
