Returning to PS and have a few questions

[Nereid]

I was wondering if their is a website that shows vehicle HP, and vehicle and regular weapons damage. Id like to compare the damages of different vehicle weapons and their HP to decide what I want to use and the firepower of the AV weapons and others. Or if their isnt a site can someone tell me the hp and the damage of the 75mm cannon on the lightning, the hp and damage of the 35mm machine gun on the liberator, and the hp and damage of the rockets on the reaver? If anyone could help me with this id much appreicate it.
