All the modern tanks in Ukraine (on both sides) have fairly wide (0.5m or greater) tracks already and so do the more modern IFVs/APCs such as Bradly and CV90. Therefore I doubt this is a concern.What kit does Ukraine need to keep the offensive going over the autumn and winter? Warm and water/weather proof clothing and boots of course, but what about vehicles? How about track width extensions for the T-series and NATO-origin MBTs? In WW2 the Germans had Winterketten, is that still a thing? Today's modern MBTs rely on deep side skirts for protection, so that might prevent track extensions.
