I have several questions on radicals in Kill-Teams.

Would a Kill-Team use Xenos or Heretic weapons?

If their weapons were rendered ineffective and all they had was xenos or heretic weapons would they use them?

If a marine killed an eldar warlock and its sword were far superior to his own, would he use it regularly?

Would they use xenos or heretic vehicles?

If their transportation was rendered useless, would they use xenos or heretic vehicles?

Would the fact that their Inquisitor is a Radical change this fact?

Would a black templar, chaplain, or black templar chaplain in the group effect this?

Would a black templar, chaplain, or black templar chaplain in the group try to kill a Radical Inquisitor leading the group?

1. Depends on the marines, the situation and probably how bad the effects of using said weapons would be to the payoff. Wielding a daemon blade just to kill a couple of 'nids is probalby not going to happen. But the Astartes could do it if it means saving the whole sector.

2. Likely but it also depends on what kind of xenos or tainted weapons that we're talking about, and the Kill-Team itself must be taken into account.

3. I think that would very much depend on the individual Space Marine

4-5. I think this works pretty much as in point 1.

6. I think that a Radical would be more forgiving and might try and request Space Marines from certain Chapters not known for their puritianism, but I'm not sure how much they can influence that part and instead get what's handed to them by the Deathwatch itself.

7. Most certainly

8. I don't think so unless it was a VERY serious case of radicalism, like summoning daemons and the like. Instead its more likely that he would bring it to the Watch Captain and so have it go through the official channels. That he would do something should however be pretty clear.

Part of the grim mission parameters of the Deathwatch in their charter and oaths is to take steps to secure the safety of mankind, and to use the weapons of the enemy against the enemy (it actually says this in the book somehwere). Only the Deathwatch is likely to do this, so in answer to most of the questions, yes they would use Xeno weapons and vehicles. They would not likely use them to the exclusion of their own gear though, but more likely make it circumstance or mission specific.

Would a Kill-Team use Xenos or Heretic weapons?

If their weapons were rendered ineffective and all they had was xenos or heretic weapons would they use them?

Space Marines do use ennemy weapons to fight for more than one reason: their weapon are less effective against the target, they need to make their ammo last longer, they have lost their own weapon or have no more ammo. (see prospero burn and the attack against the Quietude.) Even human troops can do it at time like in the Komissar Caine novel with in this case ork weaponery. For weapon from the dark power I guess it's a NO, but then if it is the only way than one SM will sacrifice hilmself for the job and if survive take all the time needed to purge his soul, and became once more pure enough or will be kill by his fellow brother.

If a marine killed an eldar warlock and its sword were far superior to his own, would he use it regularly?

Yes and no. Depend from witch chapter the SM comes from (no for a black templar for example). And other point of choice was the fight against the ennemy leader: was it a legendary duel, or just a bloody mess. If the weapon have gain some reknown or glory then maybe with proper ritual the weapon can be then use by the most loyal servants of the emperor.

Would they use xenos or heretic vehicles?

If their transportation was rendered useless, would they use xenos or heretic vehicles?

Yes. In many story (most of the time involving dark eldar but not always) SM used ennemy vehicule.

Would the fact that their Inquisitor is a Radical change this fact?

Would a black templar, chaplain, or black templar chaplain in the group effect this?

No radical inquisitor won't affect this. The SM will do it if it is the way the mission have to be done.(meaning giving the best odds of success)

As far as concerned if the BT is team leader it could be harder to make him acknoledge that using xenos weapons or vehicules is needed. But even a BT would choice mission success over anything else (that the way Sm are made). Even if he then needs to purify himself and or team mate later.

Would a black templar, chaplain, or black templar chaplain in the group try to kill a Radical Inquisitor leading the group?

If it is a sensible inquisitor then no. Inquisitor are used to cheat and decieve, make their goals disapear in a web of lie, actions and secret. But if a SM chaplain or not, BT or not find proof of heresy the guilty mzn should go for a hide. But for sure it's pretty much impossible for a SM to uncover that like in the BA books

In the third Ultramarines novel, I do believe that Captain Ventris and Pasanius use Chaos Marine weapons with notable distaste and after tearing off the Chaos iconography, but are later determined pure by the Grey Knights. So, if necessary, yes, but it takes some considerable willpower and a whole lotta cleansing.

In the 'The Chapter's Due', members of a Squad from the Second company go under cover inside a Chaos Rhino, and one of them carves the symbol of the Mechanicus into the inside to keep it running.

Captain Ventris said:

I remember that. I guess that weapons from chaotic soldier can be used as you desceribe it, but in my sentence, and I acknowledge that it was inaccurrate I was referring to demon weapon. But yes , a bolter from a chaos marine is still a bolter. It could be repulsive to use but can be use none the less if needed?

Marines of the Deathwatch are beholden to the Watch Commander first and foremost. While they are considered the Chamber Militant of Ordo Xenos, any particular Inquisitor who wants to use a Kill-Team still has to ask nicely.

So no, the disposition of any particular Inquisitor doesn't change much.

Personally, i believe that the vehicles that the Space marines use do not matter, but in a game you must take into account the size of a space marine and choose if they can fit. Whilst Rhino and Land Raider are specially made for space marines, vehicles such as a Tau devilfish or a ork trukk cannot take space marines.

However, this is entierly the game-master's decision
