This invention relates to an air inlet grille for an engine compartment of a military ground vehicle used in dusty atmospheres, e.g. the desert. The grille comprises a number of relatively thick air-guiding louvers of sinuous shape, each louver being relatively thick in the transverse direction so that the grille has ballistic properties, i.e. the ability to deflect or intercept enemy projectiles directed toward the engine disposed behind the grille. Each louver includes or contains a dust removal mechanism immediately downstream from each air-turn surface on the louver, whereby the grille is enabled to clean the dust-laden air, thereby preventing ambient dust from coating the engine andor the air passages of engine coolers and radiators.
