[Alien] Ripley and gang come back from Hadley's hope with hard evidence of the infestation. Given the cost of the colony, WY decides to attack with a special task force of Marines, instead of a nuclear strike. How would you train and outfit this team to best fight the Xenomorphs?

Normal training is fine.  A briefing on the acid blood and general xenomorph tactics is probably all the special attention that's required.  
Really the only reason the original team couldn't handle it was the loss of the dropship, which prevented them from being properly equipped.  So, you know, a reminder that these are sneaky bastards and you should keep the door closed should do the trick.
