-I found a decent private range in a city a couple of hours away that I can get training at, but do you guys know of any supplemental resources online that you would recommend as a starting point while I plan out whole weekends around those trainings?
I'd advise you to check out the YouTube and IG pages of Ben Stoeger, Joel Park, Mike Pannone (all guys I've trained with), and Rob Epifania. There's a ton of excellent information you can learn from for free. Treat it like homework; take notes, setup training sessions for yourself, utilize drills as diagnostic elements, and
write shit down. It'll likely feel overwhelming at first but dry fire practice can aid you tremendously in understanding what you need to work on. Yes, you'll have to utilize range time and live ammo but I say you can get 90% of the way there with consistent dry fire practice that has specific end goals in mind. Buy some target stands and targets; if you want steel just get it from whoever's cheapest.
-Where to get good first aid kits, or at least a good list of what your first aid kit should contain? I have my first aid and CPR so I know some basics, but I need a stop the bleed class still. Any other medical training/equipment you recommend?
In addition to tourniquets I'd recommend nasal trumpets, chest seals, QuikClot, regular gauze, surgical lube, and some gloves. I have bandaids, tegaderms, alcohol swabs, and sterile water in the one I keep in my car. I got that stuff from work so it's a bit of a cheat but I know for a fact those things are very helpful in a trauma situation. Remember that you're not EMS or ACLS "in the field." You can learn how to hang fluids, intubate, needle decompress, burp a chest seal, etc. if you want to but personally I recommend you think "slow the leaks, do what I can for ABC (airway/breathing/circulation), and get them to next-level care ASAP." Lastly, learn where your local EDs are and how to get to them quickly in whatever area you're going to be in.
-Any general advice for getting serious about combat training? What have you done to take your training more seriously and not just mag dump into piles of garbage?
I think it pays dividends to train mindset and observational skills as those relate to fighting. Get sharp with situational awareness, understanding body language and non-verbal cues, how to intelligently navigate potentially violent situations. As was said earlier ITT, the best way to deal with combat is to avoid it altogether.
If we're talking stopping fights with a firearm, I can't recommend getting into competition highly enough. The shooting skills required to win competitions are the exact same skills that people use to survive fights. Sign up for a local match and you'll see exactly what level your skills are at under pressure. Uncomfortable but worthwhile.
Finally, and it can never be said enough, get fit and strong. Stay that way. If you do all these things, which can totally be done without becoming some sort of Autistic Gray Man, you will be very hard to kill. Worth all the time, effort, and money required.
