Here is the intended replacement for the LAV-25, the Textron Cottonmouth.

Personally, I don’t know about the Cottonmouth. It is 6x6 intended to replace a 8x8 and even in the recon mode, it loses the firepower of the 25mm cannon in favor of the CROWS II RWS with .50cal and Javelin ATGM coaxial. To reload, the crew has to get out of the Cottonmouth and reload manually, exposed, not under armor as inside a turret. Now with new RWS turrets in the 30mm and 40mm cannon versions, perhaps the USMC can find a LAV-25 replacement with more firepower.
