> I have seen many user made red alert units, but have not been able to make any myself as i do not know how. Does anyone know how to create the unit images (both unit models and icons) for red alert 1, so that i can put them into either a mix or RAL file (used by TUC). Any help would be appreciated.

You can convert an existing unit (and cameo/icon) to PCX, then use an image editor like PSP to edit those PCXs. Then you can convert them back to SHP and insert them into a MIX.
