As promised here is the data i collected about infantry damage to buildings. Most of the infantry in the game will run out of ammo in exactly one minute if u hold down the fire button, but a few have slightly more time. Notably the grenadier (80s), PIC(90s), stealth black hand(100s), and probably the sniper as well (i didnt test this). I've converted all of the data into a damage/min rate and left out those i feel do mimimal damage to buildings.So without further ado, the chart:gunner/rocket soldier.....6.5/min
grenadier.................5.4375/min
PIC/Ravenshaw.............4.0/min
mobius/mendoza............5/min
patch.....................3.9/min
chem warrier..............4.25/min
BH heavy assault..........3.9/min
BH stealth................3.0/min
flamerthrower.............2.5/min
engineer..................-6.0/min
tech/hotwire..............-12.0/min
vehicles(extrapolated from earlier data)
medium tank........10.9090/min
mrls...............14.2857/min
mamoth shells......15.3846/min
rockets.....23.0769/min
light tank.........9.2308/min
flame tank.........17.1429/min
stealth tank.......17.1429/min
mobile artillery...16.2162/min
Also most weapons seem to do double damage when shot at the mct.
I hope this infomatoin helps u form new strategies and make intelligent decisions about how to take out buildings. As for me, im off to put some of my own strategies into action on the battlefield. l8r
