I am a volunteer member of my county’s search and rescue team, which I joined in January. Most of the training was provided by the county’s Emergency Service Unit, Sheriff’s office, and the Department of Natural Resources (game wardens). Since the county is rural, surrounded by state and National forest land, the primary training focus has been on emergency medical issues and learning how to do grid searches for lost hikers. I have only been called out three times since January, once for a lost hiker, a 6 year child who wandered off the campgrounds, and because I am LEO, once to help provide manpower to the local sheriff’s office to help find an escaped felon.
Since the defund the police movement, I have been asked to teach basic firearms skills, which I do twice a month. The amount of people from all professions wanting to join the volunteer team have tripled since COVID and the civil unrest. Of course the main problem, as always, is money. My county is rural and poor, with most of the income coming from tourism. I am not in the chain of command, so, I am not privy to day to day decisions, but, talking to the emergency services director, she is trying to work out mutual aid agreements with several larger counties, to have access to their instructors and equipment.
Quality rescue equipment is not cheap. Medical supplies, climbing gear, even boots have to be the best. My county supplies most of the members with a basic loadout, but, most of us have bought our own equipment. One word of advice, if you decide to do this and have to buy your own equipment, wait until after your training and first call out. You will be able to observe what others have bought and what works and doesn’t. Don’t be like this well-meaning individual who showed up with enough climbing gear to scale Everest and no bottled water when the day was in the high 90’s. He didn’t last long. I know he had been through emergency medical training, so, he knew the procedures for hydration. If you decide to join, you will encounter many well-meaning people, no matter the level of training, who have no common sense. Unless it’s all hands on deck looking for a missing child, these people are better off in a support role.
The courses you listed, seem excellent to me, covering every area you will need to know. I don’t know the cost of the course, but, we have several large churches that pay the tuition for their members who join. As always, when you are dealing with people, you will meet a few know-it-all dickheads, who are only there to boost their own egos. Ignore them, if you can, and focus on the call out.
I hope this helps a little with the background.
