Sometimes when you're reporting on events with lots of people, like demonstrations or football matches, things can get out of hand.
We started our week with training about how to cope with crowds, learning to stick together and protect ourselves and our equipment.
Hopefully I'll never come into contact with guns, but when reporting in war-torn countries, it's good to know how to avoid getting caught in the cross-fire.
Today we learnt all about weapons - the different types and what they can do.
Today, we were told all about something else unpleasant we may come into contact with in a country at war - landmines.
These are bombs underground that go off when you step on them.
They're now illegal, but you can still find them in some places where people are fighting. We discovered how to spot them.
