From the game manual:
WESTERN FRONT: THE LIBERATION OF
EUROPE 1944-45 simulates the
titanic clash between the Allies and
the last of Hitler’s unbroken might.
You may play either the Axis or
Allied forces against the
computer, or select the two player
option against a human opponent.
As supreme commander, you
direct division or corps-level
movement and combat operations,
order air missions, and control
the production of war materials
in your factories.
In WESTERN FRONT you issue strategic
level orders to division and
corps-sized units. Division-sized
units are comprised of single divisions
or brigades, which in turn are
built of smaller support sub-units
such as battalions, batteries or
companies. Support sub-units have
only one type of equipment
assigned to them. Other support
sub-units may also be assigned to
division-sized units. Corps-sized
units may have several divisionsized
units in addition to support
sub-units. When you examine units
and view combat results, you see
your assets and combat results at
the level of individual planes, vehicles,
guns, and infantry squads.
The WESTERN FRONT map is based
on an invisible hex-grid system. In
the full-map Overlord scenario, the
map spans the entire theater of
operations, from England in the
west to past Berlin in the east, and
spanning the entire front from
Hamburg to Italy. In the scenarios,
the map is confined to either the
Western European or Italian theaters.
Each hex is 10 miles across
and each turn represents 4 days of
real time.
