"Tactical" certainly has a definition. "relating to tactics; done in order to get a particular result". The military has tactics to achieve particular goals. They use gear and weapons to do this, and those things can be said to be designed and used for tactical reasons, they are as they are to assist with the tactics.
...Then the marketing departments got hold of it, and the word "tactical" alone became more used in relation to military gear than it is with any other activity that one might employ tactics for.
While it is easy to roll eyes at all the junk that is sold with the help of the word "tactical", there is a lot of other junk sold in all sorts of fields, as Silverclaws says. Just because a word gets used by marketing, does not mean that that is all the word is. The meaning came first, and is still there.
What does "tactical" mean in a civilian context? If one changed the question to" What do marketing departments mean when they use the word in relation to products?" then I think Wildgoose has it nailed perfectly. As with "professional" tools, whether the stuff really is good enough for professionals, or military or police, is another matter.
If you can imagine a 17 year old boy buying gear you can bet most of it was advertised on Ebay with the word Tactical in the description.
With a bit of luck he'll have grown out of that phase by the time he's 20 and if he's still buying it when hes 40 we most likely have a failure to launch situation and he still lives with his mum.
Maybe.
As opposed to the wool, canvas and leather hatted folk? Or the people that like tweed, or the folk who enjoy visiting the outdoors in the same trainers, football shirt and hoody they wear all the rest of the time? Should we stereotype based on wardrobe and hobby...given where we are all posting, should we cast stones?

Once...but for the last 20 years it can also be shades of tan, brown, grey, and green
Airsoft is a bigger market than "bushcraft", it is full of military style and "tactical" gear, and there are a lot of people of all ages that take part. I do not, and it isn't something I am interested in, but its a market that keeps companies like Helikon afloat, and many others who lots of people here appreciate being able to buy odds and ends from.
