The Erebonian and Rubrumian Army Corps (ERUAC) is an army formation based in both the Erebonian Empire and Rubrum. It was formed in 1912 as a contingency to counter the threat posed by the Autocratic East Europan Imperial Alliance and the Calvard Republic. The corps traces its origins from West Erebonia, during which it was under Lucian Administration as the Dominion of Erebonia. During that year, there were not enough troops from the UK to strengthen the defences on Western Erebonia so it was decided that troops from Rubrum would form up.
Throughout history, the relations between Rubrum and the Erebonian would root its strong ties from the army corp. Given that the cultures of the two countries are almost similar such as possessing a common form of English language and accent, as well as almost being similarly rooted from the Lucian Culture; the peoples of the two countries consider themselves more than a sibling despite Erebonia never being fully under Lucian Administration or a colony. This special relationship is still evident today, with Rubrum being the Erebonia's strongest trading, innovation, and investment partner. Exercises in the form of the Army Corps are still being conducted today.
The Army Corps would serve throughout the 20th Century and into the modern era. The formation of the Army Corps on 15 May is celebrated as Eruac Day, as well as the Erebonia-Rubrum Friendship Day.
