This one really benefits from the full definition
"kata perintah dalam baris-berbaris, gerak badan, dan sebagainya (seperti si...ap! maju ja...lan! berhen...ti!)"
Words of command, body movements, etc in a sequence like "ready! advance! stop!"
So it's pretty much the commands shouted out during a military drill. If anyone knows if it can be used in any other contexts, please comment.
