I've got multiple sid files that make up my county of interest.

I need to get all the sid files into one and STILL have the sid file type after merging.

Anyone know how to do this in ArcMap 10.2.2?

You can't in ArcGIS. The MrSID format is read only. If you want to output to sid, you need to purchase the LizardTech MrSID encoder, or find some other software that incorporates this proprietary encoder (I think you can write to sid with GDAL if you compile the MrSID driver against a purchased LizardTech encoding SDK).
