American Pratt Miller presented its EAMV MCA UGV, also known as Oshkosh RCV, in quite interesting combat configuration. Its armament consists of 50mm XM913 gun, which will be main armament of U.S. Army IFV and has greater firepower than gun on M2 Bradley.
Corresponding footage appeared from company announcements and visitors of this year's Ground Vehicle Systems Engineering & Technology Symposium (GVSETS 2026), where unmanned system was shown. Resulting system is presented as good demonstration of combined own developments.

Defense Express notes result is quite sizeable UGV with heavy armament. 50mm automatic gun is capable of penetrating protection of most armored vehicle samples and potentially even damaging electronics and observation devices of tank.
Worth recalling back in 2021 Pratt Miller showed EAMV MCA but with 30mm XM813 Bushmaster gun, derived from Mk44 Bushmaster and used by American military. Now apparently decided to look at the future.
50mm XM913 should become main armament of U.S. Army's future next-generation IFV replacing legendary M2 Bradley, where Rheinmetall and GDLS currently compete for contract. Thus UGV armed with it will be partially unified with mechanized units. At same time for such gun in U.S. they want drone destruction capability.
However important questions remain, like ammunition quantity in turret, especially given quite sizeable dimensions of 50mm rounds. If ammunition load proves too small, this may call into question advisability of such configuration.
Also worth mentioning protection question, as Pratt Miller UGV has large dimensions and must conduct direct combat with adversary, therefore should withstand hits. Without this it can easily be disabled, and although people will not be lost, question of advisability again arises.
Recall EAMV MCA in Oshkosh RCV-L version has mass over 3.8 tons and can carry over 3 tons payload. Declared maximum speed is 72 km/h, as well as capability to overcome 60% grade, 40% side slope and vertical steps up to approximately 61 cm.
