The game is fought on 150mm (6”) squares each square is 3Km per side, 50mm = 1Km (1:20,000)
For 15 to 20mm models we recommend that you use 1:200-300 houses and 1:144 or 1:200 scale aircraft. The idea is that the roofs of the houses should just hide the top of a tank model.
At CSO, one vehicle model represents 30-60 vehicles (a battalion), and can have a small die marker or pin on the back to show how many Strength Points (SPs) it represents. Normally one SP equals ten to twenty vehicles and a base will have an SP of 3. Platoon or company sized detachments are usually shown by a vehicle or base with a strength of 1SP marked on the back.
It is usual to represent tanks, infantry and artillery at battalion strength, and reconnaissance (recce), infantry heavy weapons or anti-tank guns at platoon or company strength if shown separately, so a battalion would usually be represented by one vehicle, or infantry BASE of 3SP. , Forward Observation Officers (FOOs) and Engineers may be shown as a specialist independent base of one or two figures with only one strength point, but are often not. The minimum unit of manoeuvre is the battalion. . If you mount your figures singly for skirmish games, it can be convenient to group them together as a battalion by blue-tacking them onto a 25-50mm wide base for speed of movement during play.
To be ordered and self supporting, place bases in contact during movement and attacks. You can see this in the picture below and in the Orders of Battle (Orbats). Terrain may cause bases in contact to slide apart. Use common sense. Do not overlap bases.
A Romanian regiment of three battalion bases and a headquarters base. Only the headquarters needs a die on it, in this case showing that the regiment can conduct three attacks before becoming disorganised and needing resupply. Models by Peter Pig
