Enter  the game, start playing as german in campain, when you are
in  the debreifing room look at the requisition points for the current
operation  (mission  is  surrounded  by  a  yellow  box ) memorize the
amount.  press  cancel  and  return  to  main  menu. Select other than
campain  press  alt+esc (win 95 pc) To return to the desktop, start MS
Word,  Open  the  saved game with word text editor (the game autosaves
itself in the last number of saved game if it was the last mission you
selected - backup the file first). search for the string "//Req points
for  operation"  -without  the  quotes  "  "- it has many strings keep
searching  the  string where u'll find the number you memorised change
it  to  1500  or more(1500 is enough). DO NOT DELETE THE SPACE BETWEEN
THE  NUMBER  AND  THE //.. if you made it undo (it's a formatted area)
NOW to get better weapons and units:

go up few lines you see the req unites allocated.. 
Type,Max and  requested if you change the type to:
73- you get the moste powerful german tank the "konigstiger"
19- a panzer tank good and fast one.
8- mark IV tank.

     Now to get more units just change the max amount to 40-50 or more
the  max  amount  is the second number after the unit code on the same
line) try not to change the reqested unit number since it deteriorates
the file sometimes.

     You can experiment for other codes.. I had no time. save the game
with  the  save shortcut and close the file.. when prompted to save in
formatted document press NO. Press ALT+TAB to return to the game press
campain- select your game(2xclick) start it and there you go plenty of
support  to smash the ennemy. Make the same for every battle where you
have little req points and units.
