Army United FC

Army United represents the Royal Thai Army and has traditionally been Thailand's yo-yo club along with the Navy and Police clubs. Up until 2010 and the name change from the Royal Thai Army to Army United, the club lacked support and had dwindling crowds, mainly supported by Army personnel shipped in for the games.

The Army team has always been a mid ranking Thai team with their biggest successes coming in the Thai Division 1 League with a championship in the 2004–05 season and 2nd place in 2009. Both of these successes have of course come after relegation from the Thai League.

The club are based in the Din Daeng District of Central Bangkok, which is the area that bases the Royal Thai Army. Up until the 2011 season, the club operated a policy of only playing homegrown talent but ditched this as the game became more professional and foreign players were brought into the team. Previously the players would work for the Army during the week and play football on weekends, somewhat different from most clubs who operated on a full-time basis.

In the 2010 season, they were reprieved from relegation after an end of season relegation/playoff system was announced to expand the Thai Premier League. They came 16th in that season and in a normal season they would have been relegated.

In 2011, rebranded Army United signed five Brazilians and surprised all expectations as they topped the TPL in the early weeks of the season. Crowds rose from a few hundred hardy souls to a season average of 5,580. Leandro Dos Santos was hitting the back of the net regularly yet the early season form petered out and Army finished in 13th position.

In 2012, most of the Brazilians had moved on but were replaced with other highly rated foreign stars. Daniel Blanco was the most impressive performer as Army flirted with the Top 6 for long periods before eventually finishing in 10th position.

The 2012 season also coincided with Army reaching the 2012 Thai FA Cup final. On the way to the final, Army was given a reprieve after they'd lost a penalty shoot-out to regional league side Trat. It turned out that Trat had fielded an unregistered player and was booted out of the cup with Army reinstated. Army United then took the scalp of runaway TPL leaders Muangthong United on the way to the final. The final itself was rather disappointing for the club with Army losing 2–1 to Buriram United.

In 2013, the club signed a strategic partnership deal with Thai-owned English club Leicester City.

In 2019, Army United decided to dissolved the club end the history of the club with 103 years.
