The best-dressed bad guys on the battlefield are taking over Assembly Required 2024. This year's event celebrates the man in the mask who brings aristocracy to the arms race — James McCullen Destro and his Iron Grenadiers.

Panel discussions, multiple vendors, customs classes, contests, prize giveaways and more await you at our 13th annual G.I. Joe convention. The Destro clan always has a plan. Make yours and prepare to join us November 8 & 9 in Des Moines, Iowa.

We’ll be marching out more event details soon.

Things are going to get messy!


A.R.M.O.R. 4 will explore the environment-defending adventures of the G.I. Joe Eco-Warriors team as they battled to save the planet, stop Cesspool’s toxic machinations, and defeat his army of sludge-spewing troopers.

Preorder your G.E.A.R. Kit here — and tune in online Saturday, June 1, 2024 as we go deep into the drainage tank and reveal everything you never knew about this early-90s sub-line.

Codename: Iowa’s origins started as an idea in a coffee shop. It’s developed into a group that hosts multiple must-attend annual events for the G.I. Joe collecting community every year — including the A.R.M.O.R. online event and our signature convention, Assembly Required.

Our mission is to cultivate an appreciation for G.I. Joe in Iowa and world-wide for the purpose of building community, preserving the brand and investing in the next generation of fans.

Assembly Required: Started in 2011 as a handful of local collectors getting together, this annual event has grown into a free gathering of fans from across the country — featuring panel discussion, custom classes and contests, guest appearances, vendors and plenty of camaraderie.

Operation: A.R.M.O.R.: Originally launched in 2020 as an online alternative to Assembly Required in the wake of a world-wide pandemic, A.R.M.O.R. proved popular enough to become its own annual event — creating an opportuning for fans world-wide to gather online for lively panel discussions focusing on deep dives into the brand.
