Sudden Strike

Press [Enter] key in game, then one of the the following cheats:

Get Free Soldiers (Bug Exploitation):

You need a medic truck, a gun (any gun that needs two soldiers), a tank, two officers/snipers, and a supply truck.

First, two officers/snipers operate the gun, and order a tank (or something else). Fire at the gun, just ONE SHOT! press C to stop immediately.

After the supply truck fixed the gun, use medic truck to take the gun, then take it off, you will find that there should be one more officer/sniper.

Repeat the step No.3, you will get a soldier each time. Of course, you may use it to for Submachine Gun/Rifleman/HeavymachineGun/General

Warning: Sometimes the game will crash if you are too greedy.

Occupying watchtowers:
Watchtowers strongly increase your units' visibility, therefore you should always keep them manned.

Alternate cheat:
Press C and V at once and then you'll get to the next level

Occupying houses:
Soldiers in houses or bunkers enjoy excellent cover. A fully occupied house can stop an entire infantry attack. However, if the enemy starts shelling the house with tanks or artillery, it’s time to evacuate so your men won’t be buried under the debris.

Repairs and experience:
It always pays off to repair damaged vehicles using the maintenance truck. Damaged units often have plenty of experience, and experience is valuable. An experienced unit shoots more accurately, sees farther, moves quicker and is harder to hit.

Capturing artillery:
If possible, leave enemy guns intact and don’t attack them with cannons, hand grenades or bombs, but rather with shooters, snipers or machinegun-equipped vehicles. After getting rid of the gunners, man the guns with your own soldiers and beat the enemy with his own weapons.
