The 'Artillery Only' meme originated within the Hearts of Iron IV community, specifically popularized by the YouTuber iSorrowProductions (ISP). It began as a community-driven challenge where the player must win a World War II simulation using only artillery units—a feat that is tactically inefficient and often results in comedic failure. The phrase has since evolved into a rallying cry for absurd gaming challenges and is frequently used to mock the 'meta' strategies of grand strategy games. Fans use this template to highlight stubbornness, insane gaming goals, or the sheer absurdity of brute-forcing a victory through firepower alone.
