Dealing with an RPG or weapons ambush is a fairly straightforward exercise in kinetic effects....or is it?
If the Jihadis are in a crowded market place and begin firing RPGs and AK's at your convoy, do you light them up with an attack helo? What if they are dig into a school, hospital or Mosque? Can you level the firing position with artillery?
The Russians used these sorts of tactics in Chechnya, and disproportionate return firepower was also the response by French Union and American troops in Indo China. These tactics, while effective in the short term (i.e. the ambush is broken), also had long term negative effects, since the survivors were not inclined to look at these forces favorably. The fact this was precipitated by the Chechnyan rebels or "Popular forces" made little difference in the minds of the survivors.
The tools of low intesity conflict are needed to deal with ambushes and the insidious IED threat, getting good relations with the locals through CIMIC and the like, and developing actionable HUMINT are keys to detecting and avoiding/springing traps before you get too far in, and good SELECTIVE use of firepower when you run out of options limits the long term damage to your cause.
