Each Entry has the Date of LAST Revision:

OCS Series (ver 3.0) (26 July 01)

1. On the Transportation Equivalents list on the charts and tables (page 1), the final bullet gives the modified Rail Cap cost for moving through interdicted or damaged hexes. This is incorrect when it comes to damaged hexes, as they totally inhibit rail movement (as per 13.3e).

2. Delete 5.7h, Reserve Mode units can spot, provided they meet the other requirements for spotters (10.0e).

3. Delete the sentence in 10.Oh stating that Air units conducting a Barrage are the only ... air units subject to Flak. There are other cases where air units get "flak'ed", see 14.9.

4. In 15.0c part B), the flak rating is the air base level minus one, not the level itself (as it is in the other rules and on the tables).

5. DUKWs can only carry items that could be carried by air transport.

6. The OCS Standard Markers illustration on page 3 of the rules incorrectly displays an air base symbol for the Hedgehog example. A real hedgehog can be seen at the start of 16.0 on page 29.

7. The Barrage Air Mission examples at the top of page 26 uses the old flak table. The first two examples roll as a +0 roll on the Flak Table. In the third example, the flak roll is done +1 (for the HQ). All examples show the attacks as undetered by flak, which is fine, but the method shown is from the old rules.

8. 4.1 Action C applies only to traces from detrainable hex back to the supply source. HQ's always draw and throw and trace with whatever MP type they happen to have on the counter (enemy ZOC's block Truckbased MP traces, do not block leg or track based, etc). (This makes all these rules the same, regardless as to whether it is SP throw, or trace.)

9. Change the definition of Attack Capable units (4.8) to "Attack Capable units are ground combat units with an attack combat strength (non- parenthetical) of zero or more in their current mode.

10. Delete the last paragraph of 13.9 and replace with "See 14.Ig for air units."

11. The index entry regarding Hedgehogs: Defender Options referring to rule 9.10d should not exist.

12. The entry on the Barrage vs. Facility Table explaining the AB result is in error in describing it as affecting only inactive air units. An AB result affects both inactive and active air units (as is the case in both rule 10.0j and the Air Unit Reduction Table).

13. Rail Conversion is listed in the index as being rule 12.3h. This should be 13.3h.

4-02 Enemy at the Gates Repl Maps (26 July 01)

1. Gumrak (Map C, near Stalingrad) is misspelled on the map as "Gunrak".

2. The road leading NW out of Pavlovsk (upper left of Map Q lost its highlight color (it's just a plain black line). It is a road like the others (and like its extension onto Map A).

3. Nizhne-Chriskaia (D37.29) should be Nizhne-Chirskaia.

4. While using these maps with EatG (i.e. before Case Blue is released), allow a w/i 1 hex set up freedom for all HQs in all set ups to account for any differences in road vs track movement rates if the HQ is found to be out of trace supply in its current location. If the HQ is in trace, the freedom does not exist.

4-08 GBII (24 July 01)

1. The Russian 37 Mech Bde (1 M Corps) has its AR reduced to 2 on its Move Mode side. It should retain its 3, like the other Mech Bdes and not be reduced the way the Tank Bdes are.

2. In scenario 7.1, the German 8th Infantry Division sets up in both B19.28 and B18.26. It should set up in B18.26 and the 87th Infantry Division sets up alone in B19.28.

3. The NKVD Border Regiment rule (3.8) refers to an effect in 3.4. This is an obsolete rule reference and there is nothing in 3.4 that affects 3.8 in the final version.

4. On the Russian order of arrival for 12 Oct 41, delete the reference to a 25th Tank Bde. The 25th Tank Bde is a 7-3-6 (not the 6-2-5 listed) and it arrives on 15 Oct 41 instead. Furthermore, delete the reference to a 6- 2-5 Tank Bde (25) in the dead unit lists in scenarios 7.2, 7.3, and 7.4.
