Not TWRA, but here is my understanding of the regulations.
Dickson is Unit L, so a hunter can legally kill 3 does a day during G/M/A season IF the hunter has a Sportsman License or itemized licenses type 001, 009 AND Type 094 permit.
Type 009 license assumes that you are hunting with a rifle/gun. The license follows the weapon you choose to use in the field.
If you are the landowner, the license/permits listed above are not needed to shoot bucks or does on your private land in Dickson today.
