.:Sub-Factions:.

When playing as America there are two different sub-factions that you can choose from, US Army or Marines Corp.

Choosing the US Army lets you play using standard American equipment from the European theater of operations.

Choosing the Marines Corp lets you play using equipment from the Pacific theater of operations with a focus on amphibious warfare.

You can choose which sub-faction you wish to play as in-game after your Mobile Construction Vehicle has been deployed into a Construction Yard. There will then be two options available in the sidebar, one for Imperial Japan and one for the JSDF. First click on the one you wish to play as, click on it again once it has finished building and then place it anywhere on the map to activate your choice. Once you have selected a sub-faction it is no longer possible to change it for the rest of the game.

Note: When the AI is playing as America it will always default to picking the US Army sub-faction.

.:Unit list:.

D-day is split up into five different "time frames" each one representing different periods before, during and after World War II. Below is a list of the units that are available to America in these time frames. There are many more units that can be randomly discovered among the battlefield or are only available in other game modes though. To see a complete database of D-day's units with detailed information on each please visit the D-day Wiki.

Note: Units with "Army" under their name are only available to the US Army sub-faction. Units with "Marines" under their name are only available to the Marines Corp sub-faction. Units without a sub-title are used by both factions.

Note: Naval units are still being worked on and are unavailable in the current release (v3.7).
