ru_disa: Hi,
I don't know how to call in artillery strikes. Here's what I do:

1) Open the map with F12
2) Go to Support tab
3) put a check mark on the battery I want to call
4) move the blue square on the map to the location I want to target
5) wait
6) nothing happens

Also, if I keep playing and then I go back to the map, there's no sign of the artillery strike I had planned a few minutes earlier.
Do I need to CONFIRM the artillery strike for it to actually happen? How do I confirm the artillery strike I have just planned on the map?

Thanks
