Executing The Fire in the East initial surprise attack.
You can execute the surprise attack by staring the game on Jun I 41 and
skipping the soviet player turn. An optional way is by starting a game on Jun
II 41 and selecting the "Options->Time Jump" command to go
back to the axis initial phase after the surprise attack combat phase has
ended.
Ignoring border rivers in Fire in the East surprise
attack turn
Rivers running along the border are ignored in the FitE initial surprise attack
turn on Jun II 41. This can be simulated in JET by selecting "Ice"
for weather zone C from the weather dialog box since ice-covered rivers don't
affect movement or combat. Just remember to melt the ice after the surprise
attack.
Executing the surprise attack turn in the middle of the game (i.e. Balkan
Front)
Start the axis surprise attack turn normally (or allied if they have an extra
turn). After the combat phase select the “Options->Time Jump” command
and go back to the initial phase and start the turn normally.
