 H1-167 is the first squadron on the east coast to receive the AH-TAC-1Z. So the big differences between the whisky and the Zulu from a maintainer standpoint is that it is about 85% commonality with the UH-1Y. So what that means is from the maintenance standpoint that reduces our logistical footprint, reduces the training requirements, and then overall the dependability of the aircraft is a lot better. From a pilot perspective I would say it's easier to fly, it's safer to fly, it reduces pilot workload and builds pilot situational awareness to a level that the whisky never could. When you look at the technological differences, you know the whisky has a lot of Vietnam air of technology in it and what the Zulu really does is brings the Marine Corps in the 21st century.
