I used Photoshop CS5 with painting over 3D model - it's very simple and fast. As example - retexture of this unit took 30 minutes of my time ))
Size of diffuse textures for all "meele" Terran units is not big, I don't know actual size, but it's not bigger then 10mb (if I will use Ultra size of textures - 256x256 and 512x512).
Added new screens with low-res of the new texture (256x256). This is Ultra quality of the texture size in SC2.

I don't like original unit's textures in SC2 - it's like cartoons. This is example of the my variant of Marine's texture.
Texture size: 256x256 original SC2 Ultra and new - 512x512 (512kb)
Texture size: 256x256 original SC2 Ultra and new - 256x256 (128kb)
