Op fire filtering

[rfisher]

It does feel almost a little too fiddly, but I'm finding that being able to stop my tanks shooting at distant infantry, or wasting valuable ATGMs on light vehicles is often worth the effort.

Just to be clear, am I right in thinking that I don't have to specify a target hex? I can just use the filtering on its own, and only use the target hex and radius option if I want to be really specific?
