Premium Content Subscriber only Soldiers taking part in Exercise Diamond Walk at the Shoalwater Bay Training Area say a new vehicle is a âsignificant leap forwardâ for the Australian Army. The Boxer Combat Reconnaissance Vehicle was used by A Squadron, 2nd/14th Light Horse Regiment (Queensland Mounted Infantry) during the 7th Combat Brigade-led training exercise. Trooper Harrison Dietrich has trained as a gunner on the Boxer CRV and said crews adapted well to the new capability. âWe have just conducted a battle run with the hatches down, which has been a first for the troops,â he said. âIt was a case of walking through the complexities of a hatch down environment. Itâs also been about adapting and trying to work out the best way to employ the Boxer.â
