Well, as you yourself allude to, The mujahadeen in Afghanistan did receive alot of crucial assistance from the west in terms of stinger missiles, without which there wasn’t a lot they could do about air attacks. I can’t really see ordinary US Citizens being able to knock those out in significant numbers under garage conditions.
As the US is currently the only superpower in the world, you would be on your own. No other country would dare to provide material assistance to you against your government.
It’s also worth remembering that the Soviet Union was in a state of economic collapse by this point, and couldn’t afford to fund a FOREIGN war. This is another relevent point. The government would be fighting for it’s own very survival on its own soil. During the Revolutionary war, as with the Soviet war in Afghanistan, the ‘foreign’ government had more pressing issues closer to home to devote their resources to. However, if the government is fighting for its very survival on its own soil, cutting their losses and withdrawing is not an option. They would have just as much to lose by not winning as you guys, and that gives them one hell of a motivation to keep fighting, no matter what the cost, because the alternative is their own destruction....
Well, according to the training I got it's possible under the right conditions using just a few hundred feet of cable, a sturdy anchor point and the critical factor is a tight LZ ringed with some tall trees. So it's a fairly narrow window absent those stingers.
But I really wasn't referring to the general body of citizens sheep. I was really talking about a huge number of former servicemen and women dating all the way back to WWII. Like my wife's dad. Retired USMC Colonel. Navy Cross, DFC and 2 Silver Stars. Once took on forty zeros by himself, downing eight before the rest of the Black Sheep arrived. Yeah he's 85, but he's got firepower I wish I had and no worries about his future. He actually sort of yearns to serve his country again. Doubt he'd be pulling LRRP missions but you'd be amazed at the level of his skills and creativity.
Remember Eric Rudolph? Guy who bombed the abortion clinics way back when? He was a little old army pfc. Standard infantry grunt. He ran the FBI's 400 man task force ragged for three years in a 40 sq mile area of the west north Carolina mountains. Sure he had tons of local help. Food etc. So would anybody resisting government tyranny. But look at Rudolph and knowing his basic level of skills, imagine what a thousand PO'd SEALs could do. Or thousands of former special ops soldiers and marine recon. These are guys trained to whip up enough explosive material to drop the Golden Gate Bridge and do so with material found locally. Could they really win? I dunno. But a good idea on how it might go can be found in a series of books written by our very own freeper Travis McGee. EFAD.
I know this, winnable or not, it's better to die on your feet as a free man than live on your knees as a slave. But.... Maybe that's just me.
