Command and Conquer: Red Alert

This is totally pointless but,when u have a transport get any type of infantry and tell it to go in.
Just before it disappears into it tell the transport to move, and the man will be left out in the water then bring it back and repeat the process. 
Also when your forces are bogged down in heavy gunfire tell them to autofire
(r2+r1)
Also before you launch a major offensive get a large amount of migs. 
Destroy all main defences and all your hopefully superior army has to do is mop up the rest of their forces
In the last soviet mission ,there is a large island directly above your base.
destroy the two bridges which are attatched to it.get a load of transports and destroy all the forces.
Then get 5 engineers and capture their  main construction base.finally,you now have the ability to build ships etc. Now use this island for your main attacks

I discovered this cheat accidentally.I made one of my units shoot its team mate.
Order one of your units to shoot a team mate or a building in your camp. in order to do this,place the cursor in one of your unit and point it to one of your buildings or unit and press and hold L1,R1,R2.
Then the once you ordered you will automatically go and destroy its teammate or the building.

Note: all codes are done on the team menu on the sidebar (the X, O, /\ and square above the building menus.) You must select then press the Cancel button (O by default) on the symbols listed. 

$1000 free cash: [] [] O X /\ O - no more worrying about your ore truck! 
Nuke: O X O /\ [] /\ - damages large buildings and units and eliminates all infantry in range!
In level: X [] [] O /\ O - can't win? 
Turn the ore into people a.k.a. gold is people:  X O /\ /\ O X - very funny! 
Chronoshift:  /\ O O [] [] X - teleport your units into the heart of the enemy base! (Do not use on infantry or dogs) 
See the entire picture: [],/\,O,X,O,/\,[] - you can't nuke'em till' you see them, right?
