The Japan Ground Self Defense Force (JGSDF) fired its FH-70 Howitzers out to 25 kilometres for the very first time while on Exercise Southern Jackaroo with the Australian Army at Shoalwater Bay Training Area in May 2019. The JGSDF conducted the long range shoot in Australia as there isn’t a military range large enough to shoot to that distance in Japan. Australian Army soldiers from 7th Brigade helped facilitate the live fire activity and were honoured to be part of this historic moment for the JGSDF.
