I don't really like disarm. I understand the motivation behind it's implementation, but it's just kind of lame.
I suggest bringing back the original stilleto (15+ sec paralyze) but make it a one-use kamikaze plane missile instead of a reusable bomber. It would have to cost less than 600m, but there would still be a cost to it's use.
The racketeer I would give slow damage instead of disarm. That way it's still a good assault-supressant but it can't be used to pin down coms and other large units like it used to.
