Thanks for the information, do you know what modeling software is used in recent versions of games like Call of Duty and Battlefield?
Why do you need to know?
Modelling tool used is irrelevant for the final look, they only impact 3d designer convenience and taste.
A safe bet is Maya and ZBrush for Battlefield though (based on the fact they ask for experience in those tools in the job listings on DICE's homepage)
And photoshop for textures...
But really, you can get the exact same result with Blender and GIMP if you don't have the budget for that (very expensive) software.
Final look depends on artist proficiency and the 3D engine used, not the 3D modelling tool.
