TCVs or WCVs—ideal choice for combat & mobility in the Himalayas?

Modern AFVs are impressively mobile. But moving 40 – 50 tonnes of armor in mountains and high altitudes needs a lot of maintenance than an average automobile. This adversely affects the combat power of the formation. WCVs are capable of self-deploying over long distances and the crew arrives in the operational areas relatively less fatigued, while TCVs look for tank transporter for deployment, making them vulnerable during moves.
