A Hesco wall that looks solid from the inside is often a free entry point from the outside. In WARDOGS, attackers rarely bother shooting through fortifications when they can simply drive a vehicle up against them and step over the top. Wall height, not wall thickness, is what decides whether your FOB holds.
Quick answer: Build your perimeter four blocks high by stacking two double-block Hesco walls on top of each other, then place hedgehogs outside the wall so vehicles cannot park close enough to be used as a jumping platform.
Why three-block Hesco and stone walls get bypassed
Three blocks is the height most builders settle on, and it is exactly the height attackers exploit. A truck or SUV parked flush against the barrier turns its roof into a step. From there, a single jump clears the top of the wall and drops the enemy straight into your base, with no damage to the structure and no noise to warn you.

The same trick works against stone walls of the same height. Two-block walls are worse still, because no vehicle is needed at all. Barrels, railings, parked cars and other clutter left around your perimeter give infantry enough elevation to vault over on foot.
| Wall height | What still gets over it |
|---|---|
| Two blocks | Infantry on foot, using barrels, railings or nearby cars as a step |
| Three blocks (Hesco or stone) | Players jumping from the roof of a truck or SUV parked against the wall |
| Four blocks (two stacked double-block Hesco walls) | Nothing on foot or from a vehicle roof |

Barbed wire is cheap at 5 build supplies and needs no FOB, which makes it tempting as a catch-all answer. Its actual description is narrow, though. It slows and injures enemy infantry, and that is the limit of what it reliably does.
You cannot crown a Hesco wall with it. Trying to place barbed wire on top of Hesco blocks returns an obstructed placement and a “can’t place on surface” warning, so the top edge stays climbable no matter how much wire you own.

On the ground, wire will not stop a vehicle either. Drivers can push straight through it. Doing so damages and deflates their tyres and slows them down noticeably, but the vehicle still arrives at your wall. Worse, a patient attacker can remove wire silently by punching it, pressing X roughly 12 to 13 times per section, with no gunfire to alert your team.
Use hedgehogs to keep vehicles away from the wall
Since the vehicle is the real problem, the fix is to deny it the parking space. Hedgehogs, the tank traps, cost 14 build supplies and block vehicle passage. Placed in a line outside your barbed wire, they hold cars and trucks far enough back that their roofs are no longer within jumping distance of the wall.

Order matters here. Wire sits closest to the wall, traps go outside it. Reverse that and drivers simply stop at the traps, which is fine, but your wire ends up behind the obstacle it was meant to support. Both items can be placed without a FOB, so an outlying position can get this layer up early.

How to build the four-block wall (“The Castle”)
The wall that ends the problem outright is four blocks high, built by stacking two double-block Hesco walls. At that height there is no vehicle roof tall enough to serve as a step, and no ground clutter that helps. Hesco pieces require a FOB and its stored build supplies, so this is a base-perimeter build rather than something you throw up mid-firefight.
| Buildable | Supplies | FOB needed |
|---|---|---|
| Barbed Wire | 5 | No |
| Hedgehog | 14 | No |
| Sandbags | 10 | No |
| HESCO Block (Small) | 10 | Yes |
| HESCO Block (Large) | 14 | Yes |
| HESCO Wall | 46 | Yes |
| Door | 14 | Yes |
| Gate | 52 | Yes |
How to check your wall actually holds
Test it yourself before the enemy does. Drive a vehicle up to the outside of the finished section and try to climb onto its roof and jump. If the hedgehog line is placed correctly, you will not be able to get the vehicle close enough to try. If you can get on the roof and still cannot reach the top of the wall, the height is right.
Then walk the perimeter on foot. Anything that gives a step up, loose barrels, railings, crates, abandoned cars, defeats a wall that would otherwise be fine, and those objects are easy to miss when you are focused on the build itself.

Supplies are finite, and a four-block perimeter around an entire FOB will eat through them fast. Prioritise the faces attackers can actually reach with a vehicle, keep the interior approaches lower and cheaper, and save enough build supplies for the mortars, launchers and repair points that make the position worth defending in the first place.
