From my three years of exchange duty with the British Army, I think the largest frustration among my coworkers was the length of time required for new equipment to be fielded. I was the subject of good natured geering or taking the p*ss as far as the "Yanks, and all their Gucci kit". There were some exceptions. The Puma and Panther showed up rather suddenly. The various programs to replace CVR(T) and associated simulation kit is one area that received some heated debate.
