It's worth pointing out that it is strongly hinted in the original Tau Codex that the Spyrer suits were provided to the nobles of Necromunda by the Tau...
Really. I only have the latest Tau Codex, so I can't look it up. But Necromunda is all the way in Segmentum Solar. The are on different sides of the galactic core. I highly doubt if the Spryer suits came from the Tau. The nobles of Hive Primus of Necromunda are fabulously rich. If any civilians could get there hands on light power armour, they could.
) and technically not even all of those bodies are wearing power armor 100 of those are scouts. I dont know how high the body count is for Sisters of Battle but even their armour is not as useful as it is with marines. 

. Or it could be as Krater says and they're using an old method of hiding numbers, even though I can't see that as being quite the same use on a galactic scale and in a warzone populated by people that can eat your brain.
