Other mods can be theoretically merged. It's lot of work ...
But it's one more, and the main reason for not install with Eastern Front mod other mods.
There are 2 EXCELENT mods for COH:TOV
Iron Cross
Blitzkrieg
It's total mods with total rebuild of units & rebalance. Rebalance is very thin (for Blitzkrieg for example) & deadliest. Battles very rapid & "eat" unhided infantry very quick. MGs is the deadly thin on the battlefield.
It's modifications is the mortal verdict to he EF units.
Battle of the bulge is revoliution for the combat process. Units simple occupy sectors & simple takes on the combat operations. NO defences. LOT of armor units. But its winter of the europe. It's no sence for merging with EF.
Other mods is not that total & not that interesting.
If you are have expirience with reballance the hole mod of EF.
