What Are Anti-Tank Barriers?
Agree: If you are evaluating defensive obstacles for a military installation, border crossing, or forward operating base, you have seen the options — concrete teeth, steel hedgehogs, wire mesh nets, excavated ditches. The problem is not a lack of choices. It is knowing which one fits your mission profile, terrain, timeline, and budget.
Promise: By the end of this guide, you will be able to match any defensive requirement to the right barrier type — with real specs, real costs, and real deployment data from a manufacturer that supplies 30+ defense forces worldwide.
Preview: We cover all five major types, compare them head-to-head on cost and effectiveness, explain the physics behind each stopping mechanism, and give you the procurement information you need to request a factory quote today.
An anti-tank barrier is any physical obstacle designed to stop, delay, or channel armored fighting vehicles. The five primary types used by modern militaries are: Dragon's Teeth (concrete), Czech Hedgehogs (steel), Tank Barrier Nets (wire mesh), MZP Putanka (low-visibility wire), and Anti-Tank Ditches (earthwork). Each works on a different physical principle and suits different tactical scenarios.
The Five Types of Anti-Tank Barriers
Dragon's Teeth
Pyramid-shaped reinforced concrete obstacles, 0.9-1.5m tall, arranged in staggered rows. Forces tanks to climb at severe angle exposing belly armor, or attempt to push through causing track damage.
Czech Hedgehog
Three steel I-beams welded at center to form six-pointed star. Rolls under tank hull when driven over, lifting tracks off ground and immobilizing vehicle.
Tank Barrier Net
Galvanized steel wire mesh, 4.0-6.0mm wire. Track entanglement — wires wrap around drive sprockets and jam track mechanism. Best balance of portability and stopping power.
MZP Putanka
4-layer progressive wound wire, 0.5-0.9mm. Invisible entanglement — wires wrap around axles and tracks. Combat-proven in Ukraine. Single-soldier deployable.
Anti-Tank Ditch
Excavated trenches 12-20 ft wide, 6-10 ft deep with vertical or reinforced sides. Exceeds tank trench-crossing capability (typically 8-10 ft). Most effective when combined with water saturation to create bogging conditions that no vehicle can cross.
How Each Barrier Type Stops a Tank
The key difference: not all barriers work the same way. Understanding the mechanism matters for procurement because it determines what vehicle types a barrier can stop.
- Vertical Obstruction — Dragon's Teeth, Concrete Walls, Ditches
Present a face exceeding the vehicle's climbing or trench-crossing capability. MBTs can typically climb 25-35 degree slopes and cross 8-10 ft gaps. Barriers exceeding these limits force the vehicle to stop.
- Track Entanglement — Tank Barrier Nets, MZP Putanka
High-tensile wires wrap around drive sprockets, road wheels, and idler wheels. Passive-mobility kill — the barrier does not absorb impact force, it uses the vehicle's own momentum to jam the track mechanism.
- Hull Lifting and Penetration — Czech Hedgehogs
Steel beams roll under the vehicle hull when driven over, lifting tracks off the ground. Pointed beam ends can penetrate belly armor — the thinnest armor surface on any MBT.
Anti-Tank Barriers in Modern Warfare
Modern warfare has not made anti-tank barriers obsolete — it has changed how they are used. The key shift: from standalone fortifications to integrated obstacle systems that combine physical barriers with surveillance, indirect fire, and anti-tank guided missiles. A barrier's job is no longer to stop a tank permanently. It is to slow it down long enough for a weapons team to engage.

FAQ
Physical obstacles designed to stop, delay, or channel armored vehicles. Five main types: Dragon's Teeth (concrete), Czech Hedgehogs (steel), Tank Barrier Nets (wire mesh), MZP Putanka (low-visibility wire), and Anti-Tank Ditches (earthwork).
Depends on mission. Permanent fortification → Dragon's Teeth (95% stopping power). Rapid deployment → Tank Barrier Net (80%, under 10 min). Covert ops → MZP Putanka (80%, under 5 min, invisible).
Dragon's Teeth $150-500/tooth, Czech Hedgehogs $200-800/unit, Tank Barrier Nets $80-220/roll, MZP Putanka $100-300/section, Ditches $200-800/meter. Volume discounts for bulk orders.
Pyramid-shaped concrete obstacles force tanks to climb at severe angles exposing vulnerable belly armor. Tanks attempting to push through risk track damage and immobilization.
Yes — extensively in Ukraine (2022-2026). Dragon's Teeth on defensive lines, MZP Putanka for road ambushes, Tank Barrier Nets for FOB protection. Modern barriers integrated with ATGMs, drones, and surveillance.
