EFFECTS OF FORTIFICATION

18 Guards Rifle Division Attack MOSCOWThe battle for MOSCOW rages

FORTIFIED troops have strong defensive positions with dug in land lines, concrete pillboxes, obstacles and stockpiled ammunition. They are not disorganised by air attack less than heavy bombers, or any artillery below 120 mm calibre prior to the attack. They count as a HEAVY target. Troops in defensive positions need not be in base to base contact. Troops only count fortified in city centre stone and concrete buildings that have been prepared for defence.

DUG-IN troops have had time to prepare shelters with overhead cover and engineering stores such as corrugated iron, mines and barbed wire. They are not disorganised by any artillery below 80 mm. They count as a MEDIUM target. They need not be in base to base contact. Troops only count as dug-in in towns centres with mainly brick buildings, or villages that have been prepared for defence.

OPEN troops are ones who are advancing tactically in to the attack and ones who have dug in hastily without engineer support, using such cover as may be available.

   Use this table above to check the minimum calibre of artillery needed to cause disorganisation on an objective, and count as effective indirect fire.

WEAPON RANGE – Table 8 
  Max Effective Range Max Harassing Range
INF SMALL ARMS 300m 1Km
INF ATK (Boyes)  200m
Lt Atk GUNS   500m 1Km
M Atk GUNS   1Km 2Km
88mm Atk etc 2Km 3Km
Up to 47mm Tk 300m 600m
48 to 76.2mm Tk  500m 1Km
81mm Mortar 3Km see note 2 below
3″ Mortar   1.5K see note 2 below
120mm Mortar 5Km see note 2 below
105mm Arty 15Km see note 2 below
150+mm Arty 18km see note 2 below
200+mm Arty 20Km see note 2 below
  1. You may wish to reduce these ranges or use other published data for specific battles.

  2. For artillery used as harassing fire – Harassing fire that “scores” causes disorganisation, but no casualties. Harassing fire only costs 1/3 of a Fire Unit and lasts for 2 hours.

  3. Buildings under artillery fire only protect as M unless they have been prepared for defence, or are reinforced concrete, in which case they may be classed as H.
