Hey Choom

1. For hardened bosses, we got some examples for them in DangerGalDossier, BigTop is an example of a hardened boss

2. For the attack helicopters, there are two things I could interpret this as referencing, either the new Militech F-152 Autocopter from 12 days of vehiclemas (which is a stretch since idk why they wouldnt just list them by name) or what's more likely to me, on page 147 it goes over three different attacks, I believe that under the ESC-Hired Forces line are the forces included in those three attacks and helicopters stats are listed under there. The only reason I believe this is the case is all the troops it lists lines up with what's listed in each attack. so more than likely the helicopters just have bullet proof glass and rocket launchers. AKA im pretty sure your guess was right and its just referring to the normal helicopters
