Check out the
40K Lexicanum about them - lots of interesting stuff:

I had a Raptor army for a while as I liked the combination of a
SM army into stealth and jungle warfare. But a few of the basics first:
- They're a Raven Guard second founding chapter.
- Original colors were blue and yellow, but are now olive drab green.
- They were supposed to take part in a crusade against Orks, but a warp storm forced their ships to crash land on a jungle deathworld. The air was so humid, the Techmarines had to modify the breathing units on all their helmets to be able to extract enough oxygen from the air.
- In the Third War for Armageddon, they were called upon to fight Orks in the equitorial jungles alongside the Catachans and Armageddon Ork Hunters.
- They were also a part of the Taros Campaign, discussed in
FW's Imperial Armor II.
When I built my army, I converted all of their boltguns and bolt pistols to have suppressors (using brass rod) and gave everyone with a
CCW the old "bowie knife"-style chainsword the old metal scouts carried. I also made heavy use of the old jungle sprues for basing. I special ordered Raptor waterslide decals from Griffon games for the army, too.
Here are some pics of my army (now sold):
