The 155mm shells being used are not crude. That was my whole point in post #3. They are sophisticated weapons, particularly when they are fashioned as Phase II IED's with more than one explosive deviced wire to the 155mm shell.
The entire point is that I believe you are not going to uparmor HummVees to withstand a direct 155mm hit.
I am not sure even a Bradley could take a direct 155. Even some Abrams have been disabled by them. That is one heck of a whallop.
There are 8,000 unarmored non-HMMV vehicles in - and 4,500 non-HMMV trucks with ad hoc uparmoring. It isn't just HMMVs. And armor helps, more armor helps more. IEDs were identified as the main threat in Iraq in August of 2003. This is not remotely a deployability issue, 15 months later. We've spent hundreds of billions on the war, and blood is much more expensive than steel. This is not remotely an expense issue. People on FR who have talked to men in the field have been talking about this for over a year - it is not remotely some MSM smear issue. We can simply do better, adapting to overcome the threat from IEDs.
