There were three roles for home-based units of the Royal Regiment of Artillery:
1. As depot or training units;
2. For providing mobile artillery forces for use in the event of enemy attack (or, as proved to be the case in Ireland in 1916, for use against insurrection);
3. For providing static artillery forces to defend key ports and coastal installations.
The listing below is the establishment of the home-based artillery as at November 1918, with the exception of anti-aircraft units.
