• Welcome to Tacoma3G.com, a free resource for 2016-2023 Toyota Tacoma owners!

    This website is the passion-project of a USMC veteran/mechanic, @Tyler. I created Tacoma3G.com to share my knowledge of this subject with others and to provide like-minded folks with a comfortable space to ask questions and create 'build threads' within our Tacoma Forums. Now, if the format of this website is confusing to navigate for you, or if you're interested in my full mission and T3G's history, check out the Help and About pages.


In military organizations, an artillery battery is a unit or multiple systems of artillery, mortar systems, rocket artillery, multiple rocket launchers, surface-to-surface missiles, ballistic missiles, cruise missiles, etc., so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is also used in a naval context to describe groups of guns on warships.
