The new wound allocation rules (i.e. closest model) open up a wonderful and easy to implement method to shoot your own troops!
SHOOTING INTO CLOSE COMBAT
Some particularly soulless generals may wish to shoot into close combat, taking advantage a hopeless melee to hold a particularly nasty enemy in place while they bring in the heavy artillery.
Shooting into a close combat is conducted the same way as any other shooting; however, just before rolling to hit, the firing unit must make a special Leadership test called a Fratricide Test to determine if they have the proper motivation to actually fire on their own compatriots. If the test is passed, the unit may fire into the close combat as desired. If it is failed, the unit does not shoot, and may not shoot at a different target this shooting phase.
In all cases, if friendly models outnumber enemy models in the close combat being fired at, the test is taken at -1.
This test will depend to a certain extent on the codex involved:
Particularly Soulless: armies composed of units that hate and despise each other and are constantly looking for opportunities to advance by taking out the opposition; alternately, armies that place zero value on individual lives. Units from these armies always test against Ld10 for Fratricide Tests, regardless of their statline value, and do not take the -1 penalty for having friends outnumber enemies.
- Dark Eldar
- Chaos Space Marines
- Daemons of Chaos (NOTE: against a unit with the same patron god, they are instead considered "Humane")
Pragmatic: these armies may have strong bonds of brotherhood, but are trained and psi-conditioned to understand tactical sacrifice and pursuit of victory over false mercy (or see an occasional salvo of fire at a friendly unit just a bit of good fun). Units from these armies test against their normal Ld for Fratricide Tests.
- Space Marines
- Grey Knights
- Dark Angels
- Blood Angels
- Black Templars
Humane: these armies have significant reluctance to firing on their compatriots even for tactically sound reasons, due to normal human emotions, being part of a dying race, or having a sense of superiority that denies the need to resort to such extreme tactics to ensure victory. Such units roll 3d6 and add the highest two for Fratricide Tests.
- Space Wolves
- Imperial Guard
If any friendly units in the unit fired upon suffer any unsaved wounds as a result of Fratricide, they must take a Leadership Test at the end of the Shooting Phase. If they pass, they continue to function normally. If they fail, they are overwhelmed by the betrayal of their comrades. Place an appropriate marker by the unit; at the end of the subsequent Assault Phase, this unit will automatically lose combat and attempt to Fall Back (even if Fearless or otherwise immune to failing Morale Tests, and subject normally to the possibility of Sweeping Advance). If the unit successfully escapes from close combat, it will continue to Fall Back until it leaves the board and cannot Rally.
