|Tau of War|
Some advice never goes out of date and the articles linked below are good examples of this. There are a number of armies that make use of firebases, so this advice on Tau of War offers some very handy advice on how to deploy and protect your guns to best effect. Bubblewrap and blocking units are key to this, and I especially like point 8 of the last article that states "A good Tau army is like an onion, it has lots of layers and makes people cry". Brilliant!
