A forced entry resistant transparent laminate comprising a combined rigid and energy absorbing laminate panel assembly having a strike side surface opposing a direction of an anticipated threat, bonded together with a transparent, ether-based thermoplastic elastomer interlayer interposed between glass or polymer layers, where the thermoplastic elastomer interlayer further includes a transparent polyurethane having an ultra-high modulus of elasticity. The energy absorbing layers include a transparent, quasi-thermoset cast from an aliphatic urethane bonded to the rigid laminate layers.
