A couple of newbie questions

[ShadowBlade]

Hey all!

I started playing WinSPMBT a few days ago, and am more or less getting the hang of it. However, I've a couple of questions:

1) How can I do an assault (I guess it's infantry-only) on an enemy unit (i.e. a tank)?

2) Is there any way to mod the dark hexes (where a unit cannot move to this turn, for instance)? I want to make them darker, since sometimes it's hard to tell the clear from the dark ones apart. Telling the difference is a piece of cake in a desert tileset, but it's quite hard in snowed mountains (i.e. The Andes).

I know I had more questions, but I can't remember them at the moment. I'll post again as soon as I recall.

Thanks in advance.
