Types of Licences
Many countries - including Croatia, Estonia, Finland, Kazakhstan, Lithuania, Papua New Guinea, Russian Federation, Singapore, Switzerland, and Turkey - have adopted a two-tier system pf licensing, whereby a person is required to obtain a permit to acquire a firearm, and will then be granted a licence to possess or keep the firearm….
In Yemen, where citizens also have the 'right' to possess weapons, civilians are not required to have a licence to hold or possess firearms, but they must have a licence to carry them.
