Infiltration suit help

[Tubblers]

Ok, I normally play a grunt sort of person. I use medium assualt and I use hacking. But I've realized that I'm bored with the usual suspense of it, and want to switch to a lighter infaltration sort of person. I just need a little help with stealth and avoidance because most of my stealth experience is in other games like the Hitman games and Thief, but Planetside is much different.
