If I had money I buy one...love those classic looking UH-1 Huey's. I wonder if they can be converted for civilian use and sale on the market?

looks like a scout vehicle rather then a IFV or Tank killer maybe a escort to.

Boeing truck-mounted laser demonstrator destroys targets through wind and fog; “photons on target”, only diesel required
Also Dallas LA Fl I decommisionned in few weeks, North Dakota commissionned then SSN/SSGN Fleet decreases to 57 units but Virginia are better, 38 weapons againt 26 and more quiet.
With 2 new Virginia by year soon this partially offset the withdrawal of LA Fl I ( 11 from 2016/19 ) and SSN/SSGN future format begins to take shape, 48 SSN, 10 less that currently but get forthcoming Virginia Block V with 66 weapons.
I can see your posted photos. I suggest you get a pro account at imgur or photobucket. You will get much more space and the cost is $3 USD a month for either one. I have both..

Boeing successfully flight tests new ceramic composite engine nozzle; reduces noise, weight and fuel use
6 September 2014
Boeing recently successfully flight-tested an innovative engine nozzle made of ceramic composites designed to reduce noise and weight and to lower fuel use. The ceramic matrix composite (CMC) nozzle, attached to a Rolls-Royce Trent 1000 engine, went through a series of tests on the ecoDemonstrator 787 Flight Test Airplane, including community noise testing, passing over a large acoustic array in Moses Lake, Wash.
This program began years ago with small samples in labs, and now we have flight tested the largest built oxide CMC structure in the world, and it performed at a very high level.
—Mitch Petervary, principal investigator
This flight demonstration is part of the five-year FAA Continuous Lower Energy, Emissions and Noise (CLEEN) program. Boeing is one of five industry contractors participating in CLEEN, an open, competitively bid, cost share program focused on speeding up development of new technologies that improve airplane fuel efficiency and decrease emissions and noise.
Modern engines have higher operating temperatures to achieve improved fuel efficiency and reduce emissions. However, these hotter temperatures are pushing the capabilities of current metallic components used. CMC technology is lighter than current metallic components and can last longer in the higher temperatures. Special CMC designs are also capable of having acoustic treatments built into them that help make engines quieter, lighter and more efficient. This technology can also enable significantly different engine designs in the future.
The 787 is scheduled to flight test more than 30 additional ecoDemonstrator technologies aimed at improving operational efficiency, reducing fuel use, and achieving quieter operation. The ecoDemonstrator program is Boeing’s development and test program that focuses on improving environmental performance.

and a very fine post T2, as I and others have noted, the extremely high temperatures of these newer more efficient engines requires some critical thinking as well as very fine materials and engineering, this IS rocket science, and this engine technology is on an extremely high level, but they are squeezing a lot of energy out of those drops of petrol, and it is an amazement to me, keep up the good work bud.
