Need Ideas for upgrades for the guards in my robbing game

Making a gaming with guards and robbers, but I litterally have no clue what upgrades to give the guards, I already have speed increase, as the guards catch the burglars by tagging them, so I need ideas for potential upgrades the guards could have

Ummm maybe extra health? Better weapons?

they dont rlly need health cause the burglars cant fight back, but now that i am thinking about it that might be a good feature, to allow burglars to have weapons
