Extra Peasants
Use the following trick to get a lot of extra Peasants (more than the campfire limit of 24) for buying whatever kind of forces you need from the Mercenary Post or Barracks. For example, put your Quarries (3 Peasants each) and Oxen to sleep. There will be that many more in your available amount when buying Swordsman or something else. Then just turn them back on when you are done and they will go back to work. This works if you do not want to wait until your Peasants fill up your campfire again, or you just need them immediately.

Put Your Enemy Inside the Castle Using an Oxe
During playing this game, you maybe noticed that you can place your oxe teraten (oxe that use to carry rocks from a stone cury to stock pile), so you can use them to put your enemy keep inside the castle... Well how? Just put oxe in a way that they can stop the main gatehouse of the enemy castle and see the all instaltion of your enemy outside the castle will be demolish, this is best trick I use with saladin and wolf in many missions and they are unable to anything, but some time they destroy the oxe so you have to put them again.
These aren't really cheat but they may be helpful...I'll continue looking! Happy gaming....Later..... -Jade

SOURCE: infinite money cheat code for red alert 2 and general

there are no available cheats for the red alert... but this thing might help you... use any army to damage your base like war factory and the barracks ... create an engineer and spy... control the engineer and the spy... the engineer must be the first one near the building.... then select both of them and use the rally point directing to the building being damage... by default the key will be "z"... you will notice then that all the units produce will be promoted by 1 rank on that building...
use it also on the barracks if you want... you can also use the spy to get money from the enemy... well gud luck
