Reaching out to those who will have to enforce Obama’s tyranny is something that should continue, but there is no doubt already a significant support within those forces. Our military combat units could easily refuse action against other Americans on American soil. Refusing an order like this isn't the same as deciding to violently resist. As soon as one man stands up I think it would sat off a chain reaction.
I also don't think federal law enforcement want anything to do with even a small armed resistance. We have to remember that our times have changed. The vast majority of Americans can't even accept the realities of war anymore which is why we haven't won a war since WW2. Most Americans will sat on the sidelines, and after any significant resistance our law enforcement agencies like the ATF would lose their will once learning what it will cost to escalate the situation.

We won in Grenada. And we won the first desert storm in the 1990's.
There will be blood.
