Ash in Rainbow Six Siege was hurt in the lore by a blast during an attack, and later story material shows she was left badly injured and in a coma.

Quick Scoop

If you meant how Ash got hurt in training , there doesn’t appear to be a clear canon “training accident” explanation in the sources I found. The more widely discussed version is that her injury happened during a combat incident in the story , not regular training.

What’s known

  • Ash is a Rainbow Six operator with a breaching-focused role in Siege.
  • Fan and lore discussions commonly point to her being severely injured by an explosion/attack in the narrative.
  • I did not find a reliable source confirming a specific training injury for Ash.

If you want the exact scene

I can help narrow it down if you mean:

  • Ash the Siege operator in lore , or
  • a real-life person/nickname named Ash from a specific training clip or post.
