Against Other Tacticals
I t seems that when tacticals meet each other, they have a tendency to stand there shooting until one is dead. This is usually born of the idea that they either have their foe on the ropes and just a little more shooting will finish them, or that they think they’re evenly matched enough, that the element of surprise will secure their victory.
The irony is that tacticals have such a wide variety of perks and weapon options, that they rarely meet on equal footing. A bolter with kraken bolts will do more damage than a storm bolter, but the storm bolter will have a greater rate of fire, while the bolter, without the targeter, will be far less accurate.
A tactical must tackle situations in a way that suits their loadout. If you have a regular bolter, standing around shooting against a tactical with a Stalker Bolter is a bad idea, for example, because they can kill you in 1-2 shots. Standing still just makes their task easier, despite how many shots you might land, you won't win. Whereas a bolter wielding tactical who flanks whilst firing, and doesn’t let their opponent get a bead on them, will fare much better.
Similarly, avoid rolling unnecessarily, as an adept sniper can hit you during or after recovering from the roll.
Conversely, if you have a Stalker Bolter, and are faced with a tactical who has a plasma gun, they will most likely be firing much more wildly than they should be. You shouldn’t just let them shoot you, but the slow rate of fire and power of the stalker's shot, means that you should choose to shoot only at opportune moments, or you leave yourself vulnerable. This means taking your time, evading their bullets and going for headshots where possible.
If your opponent has a melta gun, then you should do everything you can to not let them close range. Backward rolls, grenades, running away, whatever it takes.
