I've been pondering how the acolytes best can snoop around without raising suspision. Buying a coat or so from a local store and try to blend in to a crowd seems like a no-brainer, but certain classes seem to have a little bit more difficulty with this than others, especially the AdMech characters. Is it a must to wear the red coats as an AdMech?
Also, it seems like characters with cybernetics get such things installed either because they can afford it or they mean something to their masters. That means people with cyber-tech are above the rabble, and cyber-equipped people should be regarded with suspicion (of you're a cultist/heretic/etc). The AdMechs start with half their faces covered by a gas mask grafted to the flesh! To this, add the mechadendrites that pretty soon will sprout from the back of AdMechs. Those things tend to give them away, since they are for AdMechs only. Or can the Mechanicum be dismissed as a threat by heretics if they only care for the tech and therefore ignore the heretics (regarded as an Ecchlesiarchal problem)? One way to solve the mechdendrite issue can be to not install them in the first place, but how likely is it a player wouldn't do this?
And how do the AdMech operate? Can technicians be seen with all kinds of people regardless of what they're doing? I mean, is it likely I can find an engineer by the warp-engine on a pirate vessel? Otherwise, how can pirate vessels operate during longer periods of time? Are the prophets of the Omnissiah hardly seen by the populace (i.e. they're basically a natural part of the furniture and mind their own business until someone starts messing with the holy patterns of a construct) or do they stick out due to being very rare?
Finally, how much stuff can the acolytes lug around without getting too much attention? Pistols and smaller CC weapons seem to be somewhat common, but how will civilians react when the group carry around rifles, assault rifles, even LSWs and IG flak armour or carapace armour?
TL; DR How much attention and suspicion will a heavily armed group draw, and how do I explain and justify the presence of an AdMech?
