Dude, stop asking thousands of questions, please

. At least to try to do it on your own first. There are plenty of good tutorials which help you dive in modding and "learn it by doing". You'll soon get the grasp of how things work and will be able to do things on your own very soon.
Questions like "have you guts enny funny thing i can make?" are pretty ... odd... and don't make it look like you want to put some effort on your own in it.
Learn modding and you can do all the "enny funny thing" you want in BF42. If you then stumble upon problems or have questions while modding, feel free to ask away, you most certainly will be helped here.
"do it work add wheel on soldier?"
Of course that would work, but what would be the point?
If it's only for visual, just take the wheel geometry you want and addtemplate it to the soldier...
