Editing Warhammer 40,000/Tactics/Kill Team(8E) Guide and FAQ (section)

==I don’t know what models I should pick for my roster. Please help me!==
This advice applies to all factions. Look through all of the datasheets available to your faction (and the tactics and subfaction abilities) and the weapon lists. You’re trying to pick out useful stuff. Specifically:

*Any weapons that do more than 1 Damage. A D2 weapon is 1.5x more likely to kill a model than a D1 weapon with otherwise identical stats. So chances are these will be your primary model elimination tools, especially if they fire multiple shots and otherwise have good stats. You want as many of these as you can get. Don’t take half of the gunners available to you and complain that you can’t win.

*Any 1 Damage weapons that fire lots of shots or melee models that do lots of hits. Often they don't have the stats to beat the multidamage weapons above, but they’re reliably okay, especially against weak models.

*Melee models that can fight more than once or can charge an enemy that has fallen back assuming that they have the stats and/or wargear to leverage those advantages.

*Things that are situationally useful: stuff that stops people charging you, stuff that gives you extra mobility for zones with lots of vertical terrain, etc.

*Cheap, fast, survivable models to take and hold objectives and to control doors in arena. Access to quality chaff is a defining feature of the strongest teams, even more so in tournament settings that run custom missions or Arena.

Basic guys with basic guns are not good unless they are cheap, fast and survivable (see above) or you’ve bought all of the good models available to you and you still have points to burn. Seriously, do the math on the chances of 10 guardsmen getting at least one wound on a marine…

8-10 models is generally optimal (but it will depend on mission and opposing faction, of course). More than that and you're generally sacrificing killing power for chaff. Less than that and you're sacrificing board control (but some factions don't have any choice). The competitive missions (arena and tournaments) skew this and make board control even more important.
