Skirmisher - don't engage the enemy unless you're fairly sure you can handle them. Run away from a fight and come back better equipped.
WW, like SAIS,has a definite learning curve regarding what aliens are what level of threat, just how amazing a given device really is, etc. And because of the random setups, you can get dropped onto maps that can't be won - and maps you just can't lose on. Sometimes they're the same map with diffrent decisions on where to go!
