From the introduction to the rules:
Road to Berlin is a set of rules in the Korps Commander series, which will eventually cover all periods of warfare at a level which will allow large battles and campaigns to be fought. The series' aim is to utilize the techniques of boardgaming whilst retaining the flavour of miniature gaming.
Road to Berlin simulates actions in the Second World War on the Western or Eastern Fronts during the final two years for forces up to Corps or Army levels.
The basic units in the game are tank and mechanized infantry platoons, infantry companies, and artillery batteries. Aircraft may be in flights or squadrons, Logistics and engineers are fully covered.
A Corps level assault can easily be played on an 8' x 6' table, whilst the rules are ideal for campaign games where the action is spread across a number of tables.
