Ah Boys to Men 4 (Chinese: 新兵正传IV; pinyin: xīnbīng zhèngzhuàn IV; literally: "Recruits' True Biography") is a 2017 Singaporean military comedy film directed by Jack Neo.

After leaving the military, Sergeant Ong, Lobang, Wayang King and Ken Chow are all busy with their respective career as civilians until they are called back to serve the nation again under the Singapore Armed Forces' Armoured Formation.

It was later confirmed by Neo, who was in the midst of writing the script, envisioning it to be one centred on reservist training and the Singapore Armed Forces’ Armoured Formation unit.

A certain scene, which depicted a search-and-destroy mission against an unnamed invader, involved tons of rubber, mostly made of prop foam, and cost $270,000 to shoot.

John Lui of The Straits Times rated the film a 2.5 out of 5 stars, citing the usual "banter, brotherhood and bravery", despite "the absence of anything that resembles long-form storytelling", viewing it as "a series of loosely connected skits".

[11] A controversy sparked in May 2017 when actor Shrey Bhargava posted on Facebook calling out the offensive audition process where he was asked by the casting director to “be more Indian”.

His Facebook post went viral and polarized the nation with many offering comments in support of him and many calling him racial slurs and pointing out that he was not doing his job as an actor.
