COMBAT RESULTS DEFINITIONS:

BR = BREAKTHROUGH! All participating attacking units may tactically advance and attack (only) one more time (in conjunction with nonparticipating units which were about to attack, incidentally).
DE = Defenders ELIMINATED.
R2 = Defenders RETREATED 0-2 hexes as Attacker chooses and are DISPERSED. Possible Armor Overrun.
R1 = Defenders RETREATED 0-1 hexes as Attacker chooses and are DISPERSED. Defender may then retreat them 1 (further) hex.
D = All Defending Units DISPERSED. Defenders MAY be voluntarily RETREATed as for R1, if Defender chooses.
S = All Defending Units SPENT. Any Defending unit MAY voluntarily RETREAT up to 2 hexes of the Defender's choice, if Defender chooses, but are then DISPERSED.
- = No effect against either side.
AD = Attackers (equal to defense factors) DISPERSED.
AE = Attackers (equal to defense factors) ELIMINATED. AD for any surviving attackers.

Important: All UnDispersed German armies and corps adjacent to any Russian units attacking in a given phase ... and all unDispersed Russian armies adjacent to any Axis units attacking in a given phase ... must also be attacked.

Spent units (faced toward opponent) may not move/attack for the rest of the turn.
Dispersed units (flipped upside-down) suffer the same and also a stack of Dispersed defending units is attacked one odds column higher if half of the defending units' total defense factors are Dispersed. Dispersed units' Entrenchments are destroyed and must be rebuilt if/when the unit is again UnDispersed.

Armor Overrun: R2->DE and DE->BR, if attacking armor (minus defending armor)combat strength is 2 times the (terrain-modified) strength of defending infantry (or equal to that of Dispersed infantry). Armor Overrun may be executed against Entrenched defending units but not against Stalingrad.

Surrounded/Retreat Impossible/"No Retreat!" Orders: R1->D (and Exchange possible); R2->DE, DE->BR. The Axis Player may make this decision selectively, for each Russian attack. The Russian Player must make this decision for all his units for each entire turn during his Replacement/Reinforcement/Rail Movement Phase -- except in the case of Russian units defending Stalingrad, for which he may make individual judgments regardless of his front-wide decision for that turn.

Exchange Notes: If both sides agree to an exchange or if one side is in a "No Retreat!" situation and the other wants the exchange, some or all defending units eliminated, if Attacker can lose factors equal to the defenders' basic -- not factor-modified -- defense factors in the ratio indicated by the combat result: D2 = .5X; D1 = X; D = 1.5X; - = 2X; AD = AE.
If they can't, the result becomes just an AE.
The attacker may "bet"/risk (the factors of) just some of his units, without risking all of them, unless he wants to do that, of course.

Armor/Mech Unit "Breakdown" from -- Dispersed by -- combat die roll of 1 for German 1-2 for Russian, when attacking in the post-initial combat phases.

Retreat Routes must be away from the hex(es) attacked in that combat, and no closer to enemy units which attacked it. Defending units may not retreat into a hex adjacent to a hex from which they themselves were attacked, even if it is occuppied by a friendly unit.

Tactical Advances (for attackers only) After Combat, according to weather:
"Pure" armor and cavalry units may tactically advance up to 2 hexes as long as the first one is the defended/vacated hex.
Tac advance after combat is limited to 1 hex for all other units ... and for any unit in Mud.
Tactical advances after a Breakthrough bonus attack are limited to 1 hex for all units.
After attacking units with factors equal to the terrain-modified factor(s) of the defending units have (mandatorily) advanced into the defended hex, other attackers which participated may advance into that hex or into any empty hex adjacent to the defended one.

"Zones of Control:" Units are required to stop when they enter or move through hexes adjacent to unDispersed enemy corps or army level units -- or 2 UnDispersed German divisions -- (even if they are on the other side of a lake or a river, including the Volga). However, supply or rail movement may not be traced through hexes adjacent to any UnDispersed enemy units, unless they're occupied by friendly units or screened by unfrozen lake hexsides or the Volga.

Movement Bonus for Not Moving into the ZOC of an UnDispersed enemy unit or for Not Attacking: Axis units receive a movement bonus of 2 movement factors and Russian units receive a bonus of 3 movement factors.

AIR ATTACK:

(Each unSpent unit in the target hex is attacked separately, from the top of the stack to its bottom.)

Target is ...	Russian	German	Russian	German
Die Roll			Air Unit	Air Unit
6	D	D	EAX	EAX
5	D	S	EAX	Int
4	D	-	EAX	-
3	S	-	Int	-
2	-	-	-	AA
1	AAs	AAg	AA	AA

NOTE: Effects of German air attacks against Russian units on a major city or against Russian armor/tank units anywhere are reduced by 1 on the die roll (or by 2 against Russian units in Stalingrad), but these effects are not cumulative. (Otherwise, terrain effects in this game are cumulative.)
New rule -- Close Air Support: If the bombing German air unit has not been shot down or intercepted, it adds a (further?) shift to ground attacks against Russian units in the hex it's bombing.

NOTE 2: First (only) German bombing raids on Stalingrad (instead of interception or close air support): Rolling a "6" (against either Stalingrad hex) can cause "PANIC!!, which raises the combat odds of every German ground attack by one column for the rest of that gameturn. If both German air units have been allocated to the attack, they are both considered used, even if the first unit rolls the "6." Russian ground units in a Stalingrad hex are then bombed individually by each air unit attacking it. (And ground units are bombed individually in other attacked hexes as well.)

NOTE 3: Both German air units may be combined against any target. Not more than 1 Russian air army may attack each hex or (intercepting) German .

AIR COMBAT RESULTS DEFINITIONS:

See GROUND COMBAT RESULTS DEFINITIONS for explanations of D and S.
(Attacked units may not move as a result, though.)
EAX = Enemy Aircraft unit successfully intercepted--prevented from completing its airstrike mission--and is knocked out of the game during the next gameturn.
Int = Enemy air unit successfully Intercepted.
- = No effect against either side.
AAc = Air unit fails in mission and cannot be used during the next gameturn, if it was attacking Stalingrad.
AAg = Same as for AA if attacking any German army or armored group or corps.

German air units may bomb any hex up to 6 hexes away from a supplied Axis ground unit -- or Stalingrad at any range.
Russian air armies may attack any hex up to 4 hexes away from a supplied Russian ground unit or any Russian city not last occupied by Axis ground units. Like the German Fliegerkorps, Russian air armies do not have to be based on the map.
Air units may bomb only in the owning player's combat phase. They may intercept during the opposing player's combat or supply phase.

TERRAIN EFFECTS (cumulative):	On Combat	On Movement
Railroads	None.	Undispersed/Unspent (or replacement) Russian units may move an unlimited number of hexes. They are Dispersed at the completion of their rail movement. No rail movement in 1st turn!
Across Stream, if unfrozen	Unless any attackers are on same side, the combat odds of attacks are reduced by one column	No effect.
Across Don River, if unfrozen	Unless any attackers are on same side, Axis units' defense factors increased by a multiple while the combat odds of Axis attacks against Russian units are reduced by one column. No Armor Overrun.	+1 MvmtFctr to cross or attack Pz/Tk/Mot/Mech: +2 MFs.
Across Volga River, if unfrozen	Only infantry-type units may attack across, and their total attack factor is halved. If frozen, no effect.	All movement factor to move or attack.
Across Lake, if unfrozen	Only infantry, shock, and paras may attack--at half-strength--across. If frozen, no effect.	Movement limited to 1 hex, to cross, if unfrozen.
Entrenchments Field Fortifications	+1 defense factor for each infantry-type unit, including divisions.	None.
Hills	+1 defense factor for each infantry-type unit.	None.
.
Stalingrad	Each Russian infantry-type unit doubled on defense -- automatically Entrenched -- even when Dispersed, and Stalingrad also has an intrinsic, additional (and exchangeable) defense factor of 1 per hex. D2 and D1 combat results become just D, except for computing an exchange. For Axis, same as for Major City. For both, no Armor Overrun and always supplied on defense.	None.
.
Major City	+1-2 defense factors if matched by infantry units, plus other terrain benefits. No further fortification/Entrenchment.	None.
City	+1 defense factor for 1 infantry-type unit.	"Clear terrain," unless other terrain present.
Town	See Snow rule.	None

.
GAMETURN SEQUENCE:
Note: A unit must attack in the phase it is moved (if it ever is going to attack during that turn) and is faced toward the opponent after doing so.

A. Replacements/Reinforcements and Strategic/Rail Movement -- Dispersed.
B. Operations.
- 1. Initial Operations Phase:
  - a. Axis Player's Initial Operations:
    - 1) German Air Operations (with Russian interception opportunity).
    - 2) Initial Axis Operational Ground Movement.
    - 3) Axis Attacks and Tactical Advances after Combat, with Russian Units Recovered from Dispersal (if not re-Dispersed) and Faced toward Axis Player.
    - 4) Russian Player's Victory Determination Phase.
    - 5) Axis Units' Supply Status Determination and Effects.
  - b. Russian Player's Initial Operations:
    - 1) Initial Russian Operational Ground Movement.
    - 2) Russian Air Operations (with German Interception opportunity).
    - 3) Russian Attacks and Tactical Advances after Combat, with Axis Units Recovered from Dispersal (if not re-Dispersed) and Faced toward the Russian Player.
    - 4) Axis Player's Victory Determination Phase.
    - 5) Russian Units' Supply Status Determination and Effects.
- 2. 1st(-4th?) Reserves' Operations Phase
  - a. Axis Player's 1st(-4th?) Reserves' Operations:
    - 1) German Air Operations (by units yet to be used, with Russian Interception opportunity).
    - 2) Axis Reserves' Ground Movement (minus Movement Factor equal to Phase number).
    - 3) Axis Reserves Attacks and Tactical Advances after Combat.
  - b. Russian Player's 1st(-4th?) Reserves' Operations:
    - 1) Russian Reserves' Ground Movement (minus Movement Factor equal to Phase number).
    - 2) Russian Air Operations (by units yet to be used, with German Interception opportunity).
    - 3) Russian Reserves Attacks and Tactical Advances after Combat.
C. Refacing of All UnDispersed Units from Spent Status.

NOTE:
A unit may be operationally moved only once per gameturn by the owning player.
A unit may additionally be tactically moved after each combat it participates in, on attack or defense.
A ground unit may attack only once per gameturn (unless it gets one more Breakthrough attack upon a "BR" combat result). It may defend (and retreat) as many times as it is attacked. Once a unit operationally moves/attacks, it is considered Spent and may not do so again during the rest of the gameturn.
An air unit may be used only once, for one of the following missions, during a gameturn:

Bombing
Ground support attack
Interception
Resupply, for the Axis only.

. "STACKING" Limits:

There may be an unlimited number of units in a hex.
However, not more than 3 units in a hex may actively defend or attack. (On defense, the other units in the hex suffer the fate of the active defenders. On attack, the other units do not suffer the fate of the active/attacking units.
Of these, not more than 2 may be corps level or higher.
Of these, not more than 1 may be an army.
Thus, there may be as many as an army, a corps, and a division in a hex (or 2 corps and a division, or 3 divisions).

UNIT DATA:

Size: n. A = nth Army; n. K = nth Corps; n. PzDiv = nth Panzer Division.
Unit Factors:
- Three factors (e.g., 3-4-4): Attack Combat Factor = 3; Defense Combat Factor = 4;
  (Basic) Operational Movement Factor = 4.
- Two factors (e.g., 2-4): Attack or Defense Combat Factor = 2; Operational Movement Factor = 4.
Unit Symbols:
"Pure" armor/Panzer/tank units have tanks (or a box with an oval in it) on them.
Infantry units have the X in their box.
Mechanized (tracked) infantry have an oval superimposed on their X in their box.
Motorized (trucked) infantry have two wheels/dots underneath their unit symbol box.
Shock (infantry) have a cannon ball in the middle of their X.
Cavalry have a diagonal slash in their box.
