Manual discharge of smoke discharger rounds

[Walrus]

Hi Guys

This may seema stupid question since I have so many games / years of SP under the belt...but....

How do you manually force the discharge of SD rounds in ww2 and MBT?

I never thought you could do that at all...and have just realised that many of my opponents have been doing it to me for years.

After realising that was what weasel was doing in a current game, and being roundly laughed at for not knowing how to do it...I have been trying to set them off with no success at all.

I am confused.

I am using German Panthers and Jadpanthers in 6/45.
All have SD rounds available, their main guns are undamaged, they have available rounds to fire, have not moved.
I am trying to use the x key (and the tab at the side of screen) to target the hex to my front.

Nothing happens.
Is there a command key that I am missing?
I cannoy understand How my opponet can do this and I cannot.

Bloody hell!!
I have lost many a battle because I did not know I could do this trick.
I always thought I was seeing tank riding infantry firing smoke...or company commanders with smoke shells laying down a three shell screen.
I had no idea that players were discharging SD rounds manually.

Any ideas why I cannot do it...and by the way, a rousing chorus of "DUH!" is not going to help eh

Cheers
