- Lets us practice.
- Makes learning more fun (compared to a traditional classroom).
- We can have little competitions.
For the first time, UK troops are using a special app developed for the iPad to learn how to handle a fire mission.
That's when artillery is being fired at the enemy from several miles away.
In early trials at the Royal School of Artillery in Wiltshire, troops have learned the jargon and procedures more quickly than before, when they were sat listening to lessons from instructors.
It's hoped smartphone and tablet technology could be used to speed up training across the army.
Lance Bombardier Jason Markham from 1st Regiment Royal Horse Artillery has already served in Afghanistan and is in training for a second tour.
He told Newsbeat how it works. He said: "I'd be at the HQ - the troops on the ground would call me for fire support and they'd give me the target location and a description of the target.
"We'd use all of that information to come up with a solution.
"This has been designed to let us practise, so that when we get out there into theatre we're a lot slicker.
"It makes it more fun instead of being sat in a classroom looking at a presentation being given information.
"If you're on a course you can take this back to the block and practise with it, even have little competitions with it."[emphasis added - MQ]
Soldiers back at the CP (command post) have to learn how to communicate with those on the front line, to make sure the right weapons are fired, at the right time and at the right target.
