Here is a video posted on Facebook. It shows a 5 level course.
Stage 1: Crawl through sand and tunnel
Stage 2. Take cover and fire at target
Stage 3. Clear the room
Stage 4. Take cover behind vehicle
Stage 5. Reload weapon and clear targets
The Singapore Army uses the SAR21 bullpup. In the video it looks like there is some sort of blank firing adapter with some sort of laser system. Perhaps similar to the US MILES system. I am not sure how the targets are registering hits from a laser system but it seems to work.
