A protective shield for personnel use is provided that can be rolled into a relatively small, light weight and unobtrusive cylinder, but can be inflated to serve as a unitary shock absorbing and object deflecting shield. The inflatable structure has a generally rectangular outline, and substantially parallel front and rear broad faces of impregnated pile fabric that are relatively pliant when uninflated but substantially flat as well as stiff when inflated. A manually actuable gas cartridge device and handles are attached to the rear face of the shield, which also may include a viewing aperture covered by a foraminous member. The inflated shield provides differential distortion between the front and rear faces under impacting objects, sufficient to protect a person behind the shield by absorbing, distributing or redirecting the force of impact without significant deformation or collapse.
