Nothing can truly replicate wartime conditions, but this doesn't stop Defence personnel from training as realistically as they can.
And nothing can ever repay the sacrifice made by the servicemen and women we remember each Anzac Day, but this, again, doesn't stop those serving now from giving it their best.
Ahead of Thursday's ceremonies, Army School of Health personnel gave an insight into the environmental simulation training facility at Latchford Barracks, Bonegilla.
IN OTHER NEWS:
Warrant Officer Class One Matt Franks, who is Regimental Sergeant Major of the Army School of Health, said the centre could create a number of different weather conditions such as rain, wind or night time.
"We can have all sorts of lighting effects going off, with strobe lights, flashes," he said. "The audio system contains all different scenarios, for example, if you were walking through a marketplace overseas, if you're out in the jungle, if you're in the desert with tanks rolling past."
The facility can even hold a tank, allowing exercises like having to carry out repairs in the dark or with explosions nearby.
"To try and put people under a bit of stress while training," he said.
Lieutenant Benjamin Rainsford, the son of two military parents, has always valued Anzac Day.
"But now that I am serving, especially in the medical corps, I have just such a large appreciation of what the men and women did on that day and throughout the entire war," he said.
"To have an opportunity to pause and reflect on what they did, it's a big part of what our job is here, and it motivates us.
"We'll never forget."
