Fire Warrior Leapfrog. Though it's not really a "static" approach, you still maintain a relatively fixed fire line with this option. However, it's great for enemies who decide to sit back and shoot at you with enough firepower to be a threat to your Tau. Place your Fire Warrior Teams shoulder to shoulder as you would normally do for a static line. Next, move forward every other Team so you get a line that looks like the crenellations atop a castle wall. These moving Teams can still Rapid Fire 12", so their effective range from their original location is 18" after moving 6". However, since half of your units didn't move, they can still shoot up to 30" to provide covering fire for the moving Teams. Next turn, bring up the Teams that didn't move and continue this "leapfrog" approach up the table until you get into your desired range.

This approach can work well against slow-moving assault troops. If the remnants of such an assault team lurk just outside of charge and Rapid Fire range, your advancing line can catch them in a crossfire between two of your advancing Teams. That could mean a potential of 48 shots, which should be enough to take down even the toughest assaulters.

Markerlight Scarcity. If you've loaded up on static Fire Warriors, chances are that you don't have Pathfinders. Not only would they not fit with the them of the rest of your army, but Pathfinders would be left dangerously isolated while operating forward of your line. That means you need to find another way to get the Markerlights that will make your shooting effective and versatile enough to counter most foes.

Fire Warrior Shas'ui are your best avenues at this point. You can equip them with a Markerlight for 10 points, on top of the extra 10 you need for the Shas'ui in the first place (which you should take anyway for the sorely needed Leadership bump). You should also give him a hard-wired Target Lock for 5 points so the Shas'ui can light up different targets from the rest of his team, since they can't benefit from their own Markerlights. Or, instead of the Markerlight, you can give the Shas'ui a Drone Controller and a Marker Drone for 30 points, which has a Networked Markerlight that lets that Fire Warrior Team benefit from the Drone's targeting help (it has the same BS as a Fire Warrior). You could even throw in a Gun Drone at this point to try to force a Pinning Check with the benefit of the Networked Markerlight.

You can outfit a Stealth Team in a similar fashion. However, since the Markerlight and Networked Markerlight are Heavy 1 weapons, the Stealthsuits can't enjoy their full mobility and still help light up targets. Which, in fact, is the best reason why your static Fire Warriors should have Markerlights, since they're sitting still anyway.

Thin Blue Line. It may be tempting to spread out your firebase to cover the width of the table so you can shoot at the enemy regardless of their deployment. However, doing so exposes your force to several dangers. You invite a flank attack that will always keep at least a third of your force out of range of the attacking force, and you limit your ability to concentrate your fire for the same reason. As the first article implied, concentrating your fire is critical for Tau. One Fire Warrior Team can hurt a Space Marine Tactical Squad, but you really need two or more teams to wipe 'em out before they get into assault.

However, there is a variant of the Kauyon technique that can help. If you aren't sure where the enemy will be deploying in force, split your fire base into two lines and set them up so the outside edge of both lines are in contact with opposite side edges. Hopefully, this positioning will leave about a 24" gap between your two fire bases in the centre of your Deployment Zone. This gap will prove very tempting for your foe, who will likely advance into it (which you can help by slowly marching your lines forward if need be). The gap is in fact your kill zone, with the Rapid Fire ranges of each force covering it. If you can shift your fire bases internally to maximize the frontage facing this gap when the enemy enters it, so much the better. If the enemy doesn't fall for the trap, you might have a problem in that half of your army is facing the bulk of theirs. However, you will benefit from concentrated firepower coming from the vulnerable firebase, while the range of your Tau weapons means your other firebase doesn't have to move very far to help once the enemy commits to this move. In fact, you might be able to catch them in a pincer move, if you're fast enough.

Alternately, if you have a good idea where the enemy is deploying, you can concentrate your fire base on one side of the table to match.
