Asymmetric warfare is great but only one major army has ever been defeated in the field by this type of warefare. Generally u need a conventional force to back up it up. The VC were thoroughly defeated after TET, only the NVA keep fighting and had the ability to supply the remnants of the VC. The Iraq insurgency fell the same way. They didn't have a conventional force to back stop them and once the surge cut off supplies and the rat lines in the western desert, they fell apart.
Dude my dislike for you has waned over the last 10 days - but if you are going to play the 'resident military advisory board'.
AT LEAST GET A GRASP OF MILITARY HISTORY SINCE WWI, FFS.
The 2'nd example that you seem eager to forget (or maybe it was scrubbed from the syllabus at West-point).
The Russian (merchandised military machine) was fucked over by the same 'stone age untermenchen' - that are being talked about in threads on this page (the Mujahedin).
The Russian tank force has been suffering from major problems for a long time. The North Caucasian Military District, for instance, still operates T-72 Main Battle Tanks without night sights. But not even the more sophisticated T-80-U and T-90 have such sights, either !! (huge over-sight- or lack of it, LOLOLz) Moreover, their explosive-reactive armor was not filled with explosives & therefore could not deflect high-explosive anti-tank weapons.
It is common knowledge that tanks are extremely vulnerable in mountainous & urban areas (Fallujah - Tirkrit, etc) & during redeployment because their crews lack all-round visibility, making it difficult to spot enemy soldiers with 'RPG7's' or shaped-charges hiding in caves/ravines/behind rocks/bushes & houses.
The Dzerzhinsky Ural Railroad Car Works - Uralvagonzavod - which has developed all post-Soviet and Russian main battle tanks except the T-80, unveiled its Tank Support Combat Vehicle more than 20 years ago.
The 'TSCV' featured nine weapons systems, including guided anti-tank missiles, large-caliber machine-guns, surface-to-air missiles and 30mm and 40mm automatic rocket launchers, & was intended to be used against 'Mujahedin' forces in Afghanistan.
Yes, they had supply & re-ammunition runs - via - the 'ISI/CIA - but I would guarantee, that the 'Fadayhin' will be back in business form Iranian re-supply - before you guys have even pulled out, you will be zipping up 'body bags' as you load up the C130's & ship out.
One word = tenacity !!
