Gary: Tank Commander

Filming locations have included East Kilbride's Territorial Army (TA) Centre, Walcheren Barracks in Maryhill, Garelochhead Training Camp and the drill hall of the Glasgow and Strathclyde Universities Officer Training Corps. Clydebank has also featured as the "town centre" (episodes 1 and 3) and a location in Kirkintilloch was used for the Iraq army camp scenes (apparently, a section of land and a human-made hole were employed), both appearing in the first season.

The second series was again filmed at East Kilbride TA Centre and Maryhill, with Cambuslang's Dechmont ranges included. Locations also included the small village of Milton of Campsie, most notably the old railway line, used in the storyline that features the scattering of Gary's mother's ashes. For the second season's Afghanistan scenes, Hughes revealed in 2011 that filming was undertaken in Scotland.[8]

Most of the main characters, especially Gary, occasionally use Scots when speaking, giving rise to some humorous situations throughout the show. A notable example occurs in series 1, episode 3 ("The General"),[9] when a visiting American general struggles to appropriately use the term "ken" ("know" or "understand"). The use of Scots has not hindered the accessibility of the show to a broader English-speaking audience.[10][11][12]

Each episode contains several scenes where Gary is interacting with an unseen interviewer regarding a topic from the respective episode. The interviews are usually composed of Gary's idle thoughts and they help viewers to understand Gary. Occasionally, words or phrases (but rarely complete sentences) are subtitled in these interviews for emphasis. These subtitles are often presented with the use of subtle kinetic typography.

Each episode commences with a YouTube-style video clip (with an accompanying time meter) showing the soldiers and their antics whilst in Iraq (series one) or Afghanistan (series two) and further segments are spread throughout the episode. The clips are usually independent of the episode's plot but display the soldiers' sense of humour, creativity with equipment and their boredom during deployment.
