The trials are designed to test and analyse the system’s key functions under hot, dusty, and humid conditions and test how many soldiers the equipment can hold.

German Army spokesman Lieutenant Colonel Stefan Heydt told The Roxby Downs Sun Australia was chosen for its realistic climate.

“We are looking for hot-dry and hot-wet conditions. Australia is relatively special in that you have these conditions in ‘close’ proximity to each other,” Lt Col Heydt said.

The BOXER, an armoured personnel carrier and main focus of the trials, is being tested along with a command post vehicle called WIESEL2, a reconnaissance system called MIKADO and a command post team.

Lt Col Heydt said the army was also conducting basic tactical exercises and a live firing.

Live firing will occur at Lake Hart, 40 kilometres from Woomera and blank ammunition will be used around Shell Lagoon.

“I want to stress that we are not doing anything mysterious or top secret,” Lt Col Heydt said.

“We have full approval of the Australian Government and support from the Australian Defence Force.”

He said the German Army had invited Australian Government observers to watch the trial.

“Considerable effort is being made to ensure no harm comes to the environment in Woomera, and that local residents have good memories of our visit.”

The trials started on February 17 and will finish on March 26.

However from March 10-19, “phase two”, equipment will be trialled in Townsville.

The Australian Defence Force is providing logistic support, fully funded by the German Army, but is not directly participating in the trials.

Despite the history between the two defence forces, Lt Col Heydt said the relationship was excellent.

“We are allies in the war against terrorism in Afghanistan and we can count on each other,” he said.

Lt Col Heydt said the soldiers, who are staying at the Eldo Hotel, were enjoying their time in Woomera, and although the trials took up most of their time, spare time was used to play sports, read books and listen to music.

“We enjoy being here. We want to thank the residents for their hospitality and their kindness.”
