Everyone of us should have a vibro knife. Trax got nailed with 3 of them during Mission 6: Wing Clipping (incorrectly titled as Hard Beginnings right now) and I've only got one listed on my CS so the only thing I can think of is that he gave one to each Niil and Jex. Just a thought though, a standard knife has a difficulty of 5 to hit, a vibro knife is 15. Trax will be carrying both, as well as his neural whip.
Trax has 7 medpacks on him, but some stims would be handy as well.
For extra troopers, I'd say 2 to 4 and they stay with the shuttle on the roof (if the shuttle is staying). They can use the light repeaters to deter any ground re-enforcements that try to get in as well as keep the shuttle secure if anyone gets past us and onto the roof in an attempt to keep us from getting away.
Craig, I've got something listed as an assault rifle, ranges 3-10/75/200, 25 rounds per pack and does 6D damage but can't find any reference to such an animal anywhere. When you have a moment, can you verify that there is such a beast for me?
