I too share youre admiration for the Assyrians ,not only its military.
The Assyrian army brought in a new element of tactics and that was the so called first striking unit ,a group of specialy trained man who would deliver a first blow against a enemy that was still gathering and organising its troops and positions.
The aim of such a striking force was to create disorder and to delay the organaised resistance of there enemy.
It failed only once..during the battle of Quarqar in coastal northern Syria 858B.C
It worked perfect on open plain area's but not against the hill and mountiniouce fighters of Urartu.
