The 7-Line Army is a group of New York Mets fans, run by a New York Mets fan. Darren Meenan is the founder and owner of The 7-Line Army and The 7-Line, which is a clothing brand that makes Mets clothing and other products. When you purchase a ticket with the 7-Line Army you are given a shirt which is specifically made and designed for that outing. For home games, you are given a shirsey of the 7-Line and away games are shirts specifically designed for that city.
My first experience with The 7-Line Army was back in 2016 for the “Bronx Invasion” at Yankee Stadium, for the subway series.
