Warhammer 40,000: Sentinel Astra Militarum (1 Model)

Hold the Line

Few sights on the 41st Millennium battlefield are as iconic as a Sentinel stalking through the smoke — a lone mechanical walker scouting ahead of the Imperial advance, autocannon or lascannon swinging to bear on whatever dares to challenge the Astra Militarum's relentless push. It's a model that captures everything grimdark about the 41st Millennium in a single imposing silhouette.

What You're Getting

Games Workshop's Sentinel kit for Warhammer 40,000 builds one multi-part plastic walker for the Astra Militarum — the vast, conscripted armies of the Imperium of Man. The Sentinel is a light reconnaissance vehicle, tall and spindly by design, built to move fast, hit hard, and not stick around for a fair fight. This kit gives you the option to build either an Armoured Sentinel or a Scout Sentinel, each with different weapon loadouts and battlefield roles. Weapon options include the autocannon, lascannon, multi-laser, plasma cannon, and missile launcher, giving you meaningful choices that affect both gameplay and the model's visual personality.

This is a Games Workshop plastic kit — that means clean, detailed sprues designed for hobbyists who want to build, paint, and personalise their miniature. The Sentinel has been a staple of Astra Militarum collections for decades, and this current iteration is one of the best versions the kit has seen. It's a satisfying build for painters who want a centrepiece-scale vehicle without the commitment of a full tank, and a useful field unit for players who want cheap, mobile fire support.

Who It's For

This kit is aimed at Warhammer 40,000 hobbyists aged 12 and up — whether you're an experienced Astra Militarum general adding another walker to your motor pool, or a newer hobbyist looking for a manageable, rewarding build that doesn't overwhelm. It's also a compelling standalone model for painters who want something with strong visual character and clear detail. Assembly requires plastic glue and hobby tools; painting supplies are sold separately.

Highlights

The Sentinel's multi-part construction allows for genuine posability during the build process, so no two need to look exactly alike. The kit's detail rewards careful painting — rivets, hatches, hydraulic lines, and the pilot visible in the open cockpit of the Scout variant all give painters real texture to work with. As part of the Astra Militarum range, the Sentinel integrates seamlessly with the broader Imperial Guard army ecosystem, compatible with current 10th Edition rules and the full range of Astra Militarum supplements and codex content.
