Campaignmen at your command!

Campaignmen, Campaigners, Kampanaja, Veldtoger, they go by many names.
Learned here, the term generally refers to a generic soldier in the Unus Solum universe. They are generally armed with battle rifles, although the Shirudo and Enshawdians have been known to also use automatic weapons. Also mentioned in the above post, Lineman generally refers to a generic Campaignman.

Other regular infantry units that may be found in a campaignman unit include linebreakers and skirmishmen (I haven’t done a solo drawing of a skirmishman yet). Linebreakers are armoured soldiers which use a combination of trench guns, chemical weapons and grenades to take heavily fortified positions (see Devils Got a Gun). Skirmishmen should not be confused with sharpshooters. They can be differentiated by the type of weapon they use. Skirmishmen tend to use a scoped version of the standard infantry rifle, sharpshooters usually have higher powered single shot rifles, or even anti-tank guns.
