DF leisure owns delta force, Although recently they changed companies to some generic sports group/ charity, as apparently charities dont pay tax on imported products? (please correct me if im wrong, its only from the infomation thats come to me) Its a very shady company.
Anyway, UKPBA is DF they are one of the same, they cliam membership legitimacy through the small print when you sign the disclaimer saying your willing to join UKPBA. hence why they boast 500,000 odd members, which I wish was accurate as that would be alot of paintballers!
Truth is if DF could make more money selling tinned fruit it would be called Delta Fruit, they care nothing about paintball. Staff are paid a slave wage for the hours, and are treated badly, and they give people a distorted view of paintball, which harms real paintball companies and organisations who do so much hard work to keep our sport afloat.
