If we get lucky and Eagle Pass blows out to sea, we need to treat it as a warning of what could have been and double our own efforts to make ready.
If the US breaks up over Eagle Pass or any subsequent incident, don't be surprised to see hard borders and military checkpoints at the front lines. You might be stuck here behind enemy lines in places like FL or TX.
I know "a Fascist trained today, did you?" sounds trite and even ablist, but there is a role for everyone in any possible kind of conflict. Not all roles are physical but all roles need to be filled. No matter what your age or condition you will be able to help.
Whatever you think you would be doing, that's what you should be training for.
The abilty to handle yourself in hand to hand combat could be a lifesaver, but if there is no path forward for you in this you are NOT out of the struggle, you are just more vulnerable.
It is good to have some overland and rough ground capability too, and in each group of friends some crosstraining will be valuble. How big a pack do you need for your EMERGENCY gear? You should be able to carry it from your backdoor to a pickup point out of sight of the house at the very least. If you can't, make your go-bag lighter.
If you drive, have you ever driven off-road and on dirt? That might be the only way around a militia roadblock someday. Is there someone in your crew who can fix that car with iffy parts supplies and no outside help? Do you have spare parts?
If you bike, can you ride off-road in the woods on one or more bikes you already have, fix a problem in there and keep going? Do you have spare tires, tubes, and cables for that bike?
Biking may seem nuts in this, but during WWII bicycle use by the French Resistance was quite common. It is quiet and stealthy at night. Learn to ride with lights off at night (in a SAFE place when training please), as this can save your ass. Use your lights in all normal riding: going dark is for when the risk of attack exceeds the risk of being hit by a random motorist.
If you are on foot, how far can you hike, and carrying what? How fast can you run, focussing on with a load on?
Can you or someone in your crew navigate without GPS? The civilian version of it might be turned off or made uselessly inaccurate in conflict zones.
Do you have someone who can act as a medic? What are your food supply plans-and contingencies if it becomes hard to get?
Can you assemble your crew with the cell phone towers turned off?
For each item you will be depending on, you need spares, someone in the crew who can fix it, or better yet both.
A good idea right now is to get on that deferred maintainance starting tomorrow: Replace worn out tires, brakes, and similar and parts on bikes, cars, etc. Tune up engines, get fresh batteries for e-bikes and scooters if yours are old. Get extras for this if you expect to operate in a city. Anything that might leave you stuck somewhere should be a top priority to fix. Families with trans kids in Texas and similar states have been doing this since last year.
One advantage we get over the fash is this:
they seem to think they can train by ONLY working on their shooting. If they spend all their time at the range and no time doing anything else, then anything that doesn't involve shooting becomes harder for them. They have admitted on their own media that "the Left" can easily out-organize and out-mobilize them.
