This is a list of other .pbo map names that work well with DUWS_X_WW2. Maps without rivers are recommended as AI vehicles get stuck on the bridges.
Just grab the DUWS_X_WW2.Staszow.pbo from the google drive link in the description and rename the Staszow part to to one of these map names.
eg. DUWS-X_WW2.MCN_Neaville.pbo

Then copy to "C:\Program Files (x86)\Steam\steamapps\common\Arma 3\Missions" for singleplayer scenarios
or
"C:\Program Files (x86)\Steam\steamapps\common\Arma 3\MPMissions" for multiplayer/coop.

OR IF YOU HAVE ARMA3 INSTALLED ON ANOTHER DRIVE IT WILL BE D:\SteamLibrary\steamapps\common........

Make sure you turn on "File Extensions" in Windows File Explorer. Otherwise your file will be called MapName.pbo.pbo. Just Google: Win 10 File Extensions for a howto. Here's a link: https://fileinfo.com/help/windows_10_show_file_extensions

Smaller Maps - If you choose Random, reduce the zone size and distance. Keeps zones from spawning off the edge.

Maps with Rivers or too heavily forested/jungled - be careful placing your HQ and Zones. The AI have issues with bridges and/or deep water. Also too much forest will make it difficult to spawn zones and side missions.

Faces of War Maps

fow_map_henderson.pbo - (jungle map for Marines Vs Japanese)
SWU_Dunkirk_Bray_Dunes_1940.pbo - (Dunkirk map)

Other Workshop or DLC Maps

Napf.pbo
NapfWinter.pbo
(I highly recommend this map I would have put the mission on it by
default but wanted to limit the number of required downloads for people)

Pulau.pbo -
(another pacific map for Marines vs IJN, it has some modern military buildings in it but the undulating terrain makes for some excellent cqb jungle
warfare. 4-5 zones manually placed at around 750m to 1000m per zone can
be squeezed in if you use the central Airfield as an HQ,)

Enoch.pbo (ARMA 3 DLC MAP works really well but for the river, spawn zones manually on one side of the river or the other)

WL_Rosche.pbo

Any other maps that you find that are suitable - IDEALLY MUST NOT HAVE MODERN BUILDINGS IN IT! POST HERE!!

HOW TO FIND OUT MAP NAME

Open downloaded map in ARMA 3 editor then save, it should say the .pbo name in the top right in editor or in your arma3 MY DOCUMENTS\Arma3\missions folder (where editor missions are saved, NOT WHERE YOU PUT CHANGE MAP VERSIONS)
