Models

CrossFire (CF) requires a relatively small number of models compared to most rules systems, so it can be quick and cheap to build an army. Most players use 15mm (1:100) or 20mm (1:72) models, although anything from 6mm to 28mm will still work.

Recommended basing is 30mm squares for infantry squads, but it can still be played with other sizes (for example Flames of War rectangles) without causing significant problems.

The minimum for a decent game is probably a company of about 40-50 models on each side (15-20mm). A fairly large game would be a battalion (150 models) with 3 or 4 armoured vehicles.
