It is suggested to put this near the red army squad so when you see infantry you can fight back. But if you see antiinfantry vehicles or a panzer 3, use a tank to attack.
Remember: never attempt to use infantry to attack a antiinfantry vehicle or a panzer 3 that is not damaged. If you wanna try out, go on; it won't end good for you
