Ebbtide Supply Lines: Complete Guide to FOB Logistics and Convoy Defense

Understanding Ebbtide supply lines is the difference between a functioning military operation and watching your forces collapse from lack of ammunition and fuel. In Ebbtide, logistics isn’t an afterthought—it’s the foundation that determines whether your vehicles, aircraft, and infantry can continue fighting or become sitting ducks waiting for resupply.

A forward operating base in Ebbtide isn’t a spawn point. It’s the logistical hub that keeps your vehicles and aircraft operational in the field. Every component of your FOB—from HESCO walls to ammunition depots—has to be physically hauled to the construction site by hooklift truck or helicopter sling. The horde knows this and specifically targets these supply convoys, turning every delivery into a potential ambush. This guide covers how to establish and protect the supply lines that keep your forces in the fight.

Understanding Ebbtide Supply Lines and FOB Logistics

Ebbtide supply lines operate on a simple principle: everything you need must travel from point A to point B, and the enemy will try to stop it. Unlike games where resources appear automatically, every concrete wall section, every HESCO barrier, every fuel canister arrives via physical transport that can be intercepted and destroyed.

Supply in Ebbtide is a road, not a number. When you see a wall standing at your FOB, that concrete was carried there by something the horde could kill. When your vehicles refuel at your base, that fuel traveled along a route you either control or don’t. The Nexus—Ebbtide’s enemy force—demonstrates specific behaviors designed to disrupt logistics: ambushing convoys, cutting roads, and besieging bases. These aren’t random attacks on your infantry; they’re systematic strikes against your logistics layer.

This creates a fundamental strategic reality: build near routes you can defend, not at spots with the best cover. A perfect defensive position on a cut road becomes a tomb when you can’t keep it supplied. The consequence extends beyond initial construction—every time your ammunition depot needs restocking or your fuel point runs dry, another convoy has to make the trip. A base deep in a district you barely hold requires a convoy route you can actually keep open.

Critical Components That Keep Supply Lines Running

The functionality of your Ebbtide supply lines depends entirely on two structures: the ammunition depot and the fuel point. Without these, your base is just a wall with people standing behind it. Soldiers, vehicles, and aircraft consume ammunition and fuel, and they can only rearm and refuel at bases you control. Miss these two components and every unit has to travel back to wherever it originated, effectively removing them from the fight.

Here’s what each FOB module contributes to your operations:

Module	Function	Strategic Purpose
HESCO walls	Primary perimeter	Fast deployment, economical replacement, absorbs initial horde assault
Concrete walls	Reinforced perimeter	Slower construction, heavier cargo, protects main approach vector
Gates	Access control	Vehicle and troop movement—most common self-inflicted failure point
Scaffolding	Elevated fighting positions	Enables wall defense instead of ground-level fighting
Gun nests	Static defensive positions	Covers approaches rather than wall segments
CIWS	Point defense system	Anti-air capability that also shreds close threats
Mortar pits	Indirect fire capability	Engages massed forces beyond line of sight
Ammo depot	Rearming point	Mission-critical logistics node
Fuel point	Refueling station	Enables armored operations from FOB
Lighting	Night visibility	Inexpensive force multiplier for sentry effectiveness

The FOB builder includes warnings for the two most common mistakes that trap your own garrison. First, constructing a walled area with no entrance—troops and vehicles inside cannot exit, and the game explicitly flags this error. Second, creating vehicle entrances too narrow for passage—the builder identifies when gaps are inadequate for vehicle transit. Both mistakes occur frequently: you construct a perfect perimeter only to discover your armor is locked inside, or worse, locked outside when the horde arrives. The solution is simple: build the gate first and construct walls around it.

The CIWS deserves special attention. While classified as a close-in weapon system with anti-air capability, it serves double duty as point defense that shreds anything getting close to your perimeter. This dual functionality makes it more valuable than treating it solely as anti-aircraft defense.

Convoy Security: Protecting Your Supply Lines

Convoys represent the most attacked assets you control. They’re also the part of Ebbtide supply lines that loses campaigns. A hooklift truck carrying HESCO barriers or a fuel tanker making a resupply run is a high-value target that moves predictably along roads. The horde knows this and prioritizes convoy interdiction.

A workable escort pattern for protecting your supply lines:

Never dispatch solo trucks. Two vehicles minimum, with at least one armed escort. A single undefended truck is a gift to the enemy.

Escort with mobile firepower. Use vehicles that can fight while moving—a LAV or Humvee works; a tank that must stop to engage effectively doesn’t. Your escort needs to respond to threats without halting the convoy.

Route through controlled districts even when longer. A shortcut through fog of war is how entire convoys disappear. Add kilometers to the route if it means traveling through territory you hold.

Escort the return trip. An empty truck returning to base holds the same value to the horde as a loaded one. The vehicle itself is worth destroying, and cutting your supply line works just as well on the return leg.

When a specific route experiences repeated interdiction, the game is communicating that your base location is problematic or that you need an intermediate FOB closer to the front. Persistent convoy losses indicate a strategic problem, not a tactical one. Adjust your FOB placement or establish additional supply nodes to shorten vulnerable convoy routes.

The mechanics of Ebbtide supply lines mean that every refill represents a trip. Your base in a contested district needs a convoy route you can realistically defend. Roads are the supply system—control them or lose the logistics game.

Strategic Base Placement for Sustainable Supply Lines

FOB location determines whether your Ebbtide supply lines function or fail. Ask four placement questions in order:

Does it cover a road you need? If not, the base is a hobby project rather than a strategic asset. FOBs exist to enable operations and secure logistics routes. A base that doesn’t support either is wasted resources.

Can a convoy reach it without crossing ground you don’t hold? If the answer is no, plan the escort force before constructing walls. A base you can’t supply is a base you’ll lose.

Is there a second approach? The horde stacks and climbs. A FOB with one fortified wall and three open sides isn’t a defensive position—it’s three separate problems. Consider multiple approach vectors during site selection.

What happens when you abandon it? A FOB in a district about to fall becomes a gift of materials and structures to the enemy. Sometimes the correct decision is stripping the base and pulling back rather than defending an untenable position. Don’t trap resources in a location you’ll lose anyway.

The interplay between these questions and your Ebbtide supply lines is direct. A base positioned at a road junction inside a district you control, with visibility to a second approach, supports defensible convoy routes. That same base located one district deeper into contested territory transforms every resupply run into a major operation requiring significant escort forces.

Base placement also affects what happens when supply lines get cut. A FOB near your established logistics hub can receive emergency resupply relatively quickly. A FOB at the end of an extended supply chain becomes isolated rapidly when convoys stop getting through. Factor convoy transit time and route vulnerability into placement decisions.

Build Order for Your First FOB

Proper construction sequence ensures your base becomes operational quickly while maintaining defensive capability during the vulnerable building phase. This build order prioritizes logistics functions that keep Ebbtide supply lines flowing:

1. Pick the ground. Select a road junction inside a district you control, with visibility to a second approach vector. This site selection determines everything that follows.

2. Gate first. Make it wide enough for vehicles, positioned on the side facing your supply route. Building walls first then trying to fit a gate is backwards—you’ll trap your own forces.

3. HESCO perimeter. Construct around the gate with concrete walls on the exposed face. HESCO deploys quickly and costs less to replace; use concrete where you expect the primary assault.

4. Ammunition depot and fuel point. Build these before any weapon emplacements. Everything else stops functioning without them. These are the core logistics nodes that justify the FOB’s existence.

5. Gun nests and scaffolding. Position on walls covering the approach rather than the wall line itself. Defensive fires should engage threats before they reach the perimeter.

6. CIWS and lighting. Install once the base is functional. CIWS provides point defense and anti-air coverage. Lighting is inexpensive and dramatically improves what sentries can identify at night.

7. Mortar pits last. Indirect fire represents a luxury until the base can defend itself. Mortars answer masses forming beyond line of sight, but only matter if the FOB survives direct assault.

This sequence ensures that your Ebbtide supply lines begin supporting operations as early as possible. The ammunition depot and fuel point become active before defensive structures are complete, meaning units can begin using the FOB for logistics even while construction continues. Defensive elements come online progressively, reducing the window of vulnerability.

Frequently Asked Questions About Ebbtide Supply Lines

What happens if I build a FOB without an ammunition depot or fuel point?

Your base becomes a walled position without logistics capability. Units cannot rearm or refuel there, forcing them to return to their origin point for resupply. This defeats the primary purpose of establishing a forward operating base.

Can helicopters replace ground convoys for supply delivery?

Helicopters can sling-load FOB components and supplies, offering an alternative to hooklift trucks. However, helicopter transport doesn’t eliminate vulnerability—the horde targets helicopters just as aggressively as ground convoys, and you still need to protect the delivery.

How do I know if a convoy route is too dangerous?

Repeated convoy losses on the same route indicate the path is compromised. When a specific route experiences consistent interdiction, either establish an intermediate FOB to shorten the vulnerable section or choose a longer route through districts you control more firmly.

Should I abandon a FOB that becomes difficult to supply?

If convoy losses make resupply unsustainable and you cannot secure the route, consider stripping the FOB of valuable components and pulling back. A base you cannot supply will fall regardless of its defensive strength. Sometimes withdrawal to a defensible supply line is the correct strategic decision.

Does FOB size affect supply requirements?

Larger FOBs with more weapon emplacements and defensive structures consume more ammunition during engagements. This increases resupply frequency. Consider operational tempo and expected engagement intensity when sizing your FOB—a massive base far from your supply lines creates logistics problems.

Understanding Ebbtide supply lines transforms how you approach base building and military operations. The convoys that deliver HESCO barriers, concrete sections, ammunition, and fuel are as important as the bases themselves. Protect them, plan routes carefully, and position FOBs where supply lines can actually reach them. Master logistics and you master Ebbtide.
