The BTS-4 is a Soviet tracked armored recovery vehicle family built around tank-hull recovery work: towing disabled armor, winching stuck vehicles, lifting heavy components, and supporting field repair teams. Ukrainian and Western reporting describes upgraded BTS-4 vehicles with T-54/T-55 hull lineage, a front crane, dozer blade, and heavy winch package, while visual-loss records document BTS-4-family vehicles on both sides of the Russia-Ukraine War and one BTS-4 captured from Syrian regime forces in 2024.

Recovery Equipment

The upgraded Ukrainian BTS-4 reporting gives a useful snapshot of the family role: a tank-hull recovery vehicle intended to pull, lift, clear, weld, and support armored units in the field.

Lifting

A front-left hydraulic crane was reported with a 12-tonne lift capacity for heavy armored-vehicle components.

Recovery Pull

The upgraded package was reported with a 100-tonne traction winch, 200 m of cable, and an auxiliary winch for cable handling.

Clearing And Support

A front dozer or stabilizing blade, towing equipment, welding gear, and field tools support vehicle extraction and repair tasks.

Variants

Public sources use BTS-4 as both a base vehicle and a family label; several suffixes identify donor chassis or later modernization packages.
