Children's imagination is very funny sometimes. My son in particular would always gather things and put it in a backpack or a box and he calls it survival kit. Inside the bag or box, you would find band aid, alcohol, whistle, compass and other things including food. Then he would demonstrate how he would survive just in case a bad guy or an animal would attack him. It is hilarious to watch him.
He always wear his Dad's military hat and he would announce that the "Soldier Boy" is arriving.
