Nobody was ordered to take an untested drug. That's not why he was charged.

This guy encouraged troops to refuse orders to help distribute vaccines, and there's nothing unlawful about helping distribute vaccines.

The very first sentence in your own article:

A soldier who called on his fellow military personnel to refuse helping with the distribution of COVID-19 vaccines has been charged with an offence related to mutiny.

And if reading the article is too much to ask, then from your own submission title:

called on troops to refuse vaccine distribution

THAT's why he was charged. It had nothing to with anyone being ordered to take a vaccine. Stop being crazy.
