On June 4, 2013, Portnoy announced via Adrenaline Mob's Facebook page that he would be playing four more shows with the band before departing. Portnoy cited scheduling conflicts that prevented him from being able "to fully commit to the band's future activities at the moment". On December 3, 2013, the band announced that their second full-length album would be released on February 18, 2014, in North America and on February 24, 2014, internationally, and would be titled Men Of Honor. Portnoy was replaced by A. J. Pero of Twisted Sister. On August 4, 2014, Moyer informed his fans via Facebook and Twitter that he would not be joining Adrenaline Mob on an upcoming planned tour. In response, Adrenaline Mob announced that they were in search of a new bass player, effectively ending Moyer's tenure with the band. Shortly after, the band selected Erik Leonhardt as its new bass player.

The next day, the band performed in New Jersey with several drummers filling in for Pero, including Chad Szeliga, Johnny Kelly, and former Adrenaline Mob drummer Mike Portnoy. On March 22, 2017, the band announced the release of a new album called We The People, with its title, album artwork and some songs inspired by the 2016 United States presidential election.

On July 14, 2017, while traveling to St. Petersburg for a concert, the band's RV had pulled off I-75 in Micanopy, Florida due to a flat tire. It was hit by a tractor trailer. Later that night, former drummer Mike Portnoy confirmed via Twitter that bassist David Zablidowsky had been killed. Band members Mike Orlando, Russell Allen, and Jordan Cannata were also seriously injured in the accident.
