norway attacked, page-84

"... apparently there was an anti-terrorist exercise on a few days before...."

Yep, if you get caught up in a terrorist attack in Norway there is always the rapid response unit to come to your rescue.

After more than 100 emergency calls were received for help against the mass shooter - the rapid response unit was activated and arrived in record time -> one and a half hours later.

Tactical move -> wait for ammunition to be exhausted!
