Designating your force ragtag gives you access to more vehicles, but your maintenance cost per vehicle increases. Ragtag adds and extra vehicle for every 2 you have. However, a 1/3 of each vehicle type should be different in type, armour etc.
Camp-followers are a resource for morale, maintenance and replacements and slow down the movement of the base camp or base column. They, however, consume more supplies and if they suffer losses in combat (i.e. your base camp is attacked) they either cause a devastating loss on morale or increase the vigour of the troops. The higher the number of camp-followers in the base camp the more likely they are to be lost.
Most players will start with fairly good tech, but ubertech is only gained through mission success.
Splitting columns into flying-columns
A player may choose to split off up to two flying-columns from their main column. Flying-columns operating away from the main column will have limited versions of support, such as recovery, maintenance, medical etc. A flying-column moves faster than a base column.
