I don't think I can keep up with this speed of posting. Sorry, y'all.

I have to say I almost agree.

Unlikely...there's far worse with you lousy rabble.

1) "Independent of the conventional Imperial Guard Hierarchy, Commissars are instead attached to the Departmento Munitorum's Commissariat and are formally part of the Militarum Tempestus."

There are plenty of examples of Commissars executing members of other military branches (like various PDF's) in disciplinary matters in the fluff of 40K. And you forget that Frateris Militia are technically civilians.

2) "The existence of the Frateris Militia is tolerated due to the fact that they have no formal connection to the Ecclesiarchy: they are no more than faithful Imperial citizens eager to prove their dedication to the Imperial Cult."

3) Thus, based on your own reasoning, John is totally subject to the authority of a Commissar.

4) EDIT: Not to mention the fact he's just been conscripted.

@Andreyich I) the rp is following a newly made regiment of imperial guard not some rabble mob the ecclisarchy threw together to fight some battles. Your character would not accompany said regiment on their new adeventures if he was not recruited into the regiment. II) Also Inquisition is most powerful of all and they stand apart from everyone.

@Andreyich technically a inquisitor could exterminatus a shrine world if he felt the need and not have to get permission from the ecclisiarchy. Inquisitors really answer only to themselves

@Andreyich

I) You have a single civilian with a gun. Whom can't authorize any connection to the Ecclessiarchy - else its BLAM to the nearest Priest who allowed it. Since Men under Arms is HERESY!

II) The Ordo Hereticus has been charged with watching over the Ecclessiarchy - and they can easily BLAM or EXTERMINATUS any planet they wish. Look at the War of Disbelief, if you don't believe it.

III) And look at the Imperium as a whole. Do you think, any trigger happy civilian would be wagered over a Imperial Guardsman? As easily as some Priest can make-up a story - said IGs can easily make-up a story of you spouting HERESY and a Commisar BLAMing you for it.

IV) And then its a Commisar + the IGs + all their arnaments vs your priest with his chainsword. I am wagering of the Imperial Guardsmen here - since they aren't the Emperor' Hammer for nothing.
