calls for repairing or discarding things that are not broken. In the event something is slightly broken, the preferred option is to refer it to a consultant or specialist who will (a) tell you what you knew all along and (b) offer you a 'plan' to 'fix' the problem -- realizing of course that said consultant has no vested interest in your success or failure. This invariably involves throwing money at all problems and a consultant or specialist who laughs all the way to the Bank while the former minor problem exacerbates and morphsd into a larger and more complex problem.

The US Army training process is an excellent example of this...

Thus, for the topic at hand, failure to be prepared to conduct warfare in all its permutations caused us to lose focus generally, the Intel folks to get enamored of gadgets instead of their job, and our various communities to fight for more dollars by doing whatever seemed likely to attract the most money. Note that latter is NOT the same thing as doing what was obvious to a fifth Grade Student what was probably needed...

So, Yeah, you and 120mm are both correct. The HTT are needed and they do fill a vacuum caused by improper focus.

(Thank you both for allowing my morning rant!)
