Warhammer 40k fluff thread VI: They see me Ward'en, they haten

[Cheesegear]

1. How nimble are Space Marines/How much would power armor hamper their nimbleness?

Power Armour increases their dexterity and ability to jump and move around. That's kind of the point of Astartes Power Armour, rather than the kind that Inquisitors and things wear.

What they don't have in Power Armour, is fine motor skills. Being as they have big, metal, cement hands. Everything needs to be made bigger for a Marine.
And, in a recent novel (for the life of me I can't remember which it is), a Marine has to snap off the trigger guard of a looted gun so he can actually put his finger on the trigger.
