The fact of the matter is that no one expects another situation like Iraq. Don’t believe it? Check the historical record. For some pretty unique reasons, roadside bombs have been used more extensively in Iraq than in past wars.
Bombs and money all over the place inside Iraq fueled this tactic. So remember this, if in the years to come we up-armor everything on wheels as a lesson of this war, we will be preparing for the last war--and wearing out the heavier vehicles and failing to spend money where it is needed for the future threats.
