I would not knock "old technology".
Consider what the Afghans did to the Russians in the 1980's with "old technology"
Consider what Iran did to Iraq with "old technology" in the 1980's
Consider what Iraq did to the US with "old technology" during the Invasion of Iraq.
It is dangerous to underestimate what a motivated enemy can do to you with "old technology".
It does not matter much whether you are killed with a 2010 Hell-fire missile or killed with a bundled WWII ordnance IED.
It is not about the technology but the motivation of the soldier to his or her cause that wins battles.
