Defusing a bomb by hand tells you a lot about the enemies ordinance abilities.
From the components and make up you can discern the suppliers and the maker, all bomb makers (like watch makers) have a style if you have I.E.Ds made of differing styles within Helmand then you can deduce that you have 5 different bomb makers (which is a military specialism).
Helicoptering troops around is not the best way to gain control of the area, we need feet on the ground, if we defeat them in battle (we do) if you demonstrate control in the area by walking around you start to influence the people.
In Vietnam the Americans controlled the towns (sort of) and the Viet Cong the countryside this was because they were unwilling and unable to engage the Viet Cong in the field, to understand the failure and the difference between the two tactics look at British policy in Malaya in the 1950s, we actually pioneered the use of helicopters in warfare.
The trick is to invest in an idea that is better than the Taliban's, the trick is to convince the people that opposing the Taliban is worthwhile and productive, the trick is to overcome the latent cultural mysoginy in the area and make the people see that educating your daughters will increase the wealth and well being of your whole family.
The women want change within their Islamic identity, to deliver it will take time, the Taliban view us as indolent and soft unsuited to the hardships of a long war, are they right?
