Your likely want to look for “Level 3-A” plates for armor such that it can take an AK round. These plates fit into a “plate carrier,” usually the camo outer layer with MOLLE for attaching whatever. Price wise you’re starting around $500 for a set of plate (chest, back, sides) (in America at least where these are common and domestically produced) You can get further, with coverings for arms, neck, and groin though they are not quite as typically used. As for helmets, more or less whatever your host nation uses for their military.
