1) Marksman ship can't tell the difference if it is combat or competition - marksmanship is marksmanship
2) Combat - what is combat? There are no magical way of putting a bullet into target. It is called marksmanship
3) "Tactical" - if it is referring to personal technique s- like all these youtubes out there on how to walk, how to cut the pie. If you can find it on youtubes, you already get 80% for free. Like watching cooking, tennis, biking..... youtubes. If you can't find on youtubes, most likely your Ex-special warfare instructors won't teach you either, because it is 1) irrelevant to civilian, or 2) because you will need to pass the selection process and attend the course to actually understand and execute some of these stuff. It is meaningless if dude is completely gassed out after 1 flight of stairway or sprinting 20m. If you really want a course on this, it should not be called a "shooting " course, it is a course on CQ technique, a part of a much larger curriculum
4) Well, 3) is pointless. most people cannot even line up properly at the super market without someone pointing at the check out counter. Everyone wants to do the fun part like airsoft, where the action happens after plenty of coffee. As soon as there are more than 1 person involved, they start hating each other and play lone rangers. This means any "meat" of any real "combat" "tactical" training cannot happen with random dudes signing up for these course. A football team with a 1 hour shooting lesson will be a way more effective combat team right off the bat than a bunch of gun guys who do not like working with other people and don't play team sports.
5) so just lets skip combat and tactical, and just learn what one can do - marksmanship.
If the intention is to be a professional in certain trades, there are courses for those specific trades. Yes, it should be a combination of "shooting/marksmanship" + the trade course. Anything that mixes marksmanship with the trade specific component is suspicious IMHO.
