In my NS days, I had to go overseas to the jungles of Brunei for a Jungle Survival Training Course. There was a team of about 5 of us sprawled out at a site of about 2.5 square km.
The first day involved chopping down trees to build my shelter and during one of my breaks, I decided to be a bit adventurous and did some scouting around in the jungle to take a look at the surroundings. After walking around for about 15 minutes, I turned round to go back but I realised that nothing looked familiar!
Luckily I managed to compose myself and looked around for more details. I saw a hill that looked familiar (but in hindsight, I think all hills look the same if you’re lost in the jungles…) and as I trekked towards it, I managed to find myself back. Whew!
