When the guard player rolls the dice, and if the guard player rolls doubles, does it explode or does the guard never get to roll exploding dice?
The security guard gets exploding doubles just like the escape officers.
Also can guards move from outpost to outpost on the same turn?
No: when you move a guard from an outpost, you can only move them to the Commander's Office. Guards in the Commander's Office can't be used until they're returned to the Barracks, which happens at the end of the security officer's turn.
