Heat?
 

I've 82mm B10 RCL with 8 rounds of HEAT. HEAT as I understand it is high explosive anti-tank so why can't I direct fire it using the w key against an armoured target? I keep getting the message 'Unit has no direct fire target selected'

Re: Heat?
 

You have to first select a target to be able to use a specific weapon with the W key. The above message appears when your unit hasn't got a target "locked on" so to speak (lower left corner, see if the target is a unit or none). One thing you can do is press the T key, cycle through the targets to the one you want to shoot and press T again. Then, you can use the W key against that target.

That worked, thanks.

I had thought I done that but obviously I didn't
