Hell Let Loose: Vietnam Boat Tactics: Riverine Assault Wins

Win hell let loose vietnam boat tactics with coordinated riverine assaults. Coordinate tanks, mortars, and recon squads to push objectives from waterways.

Mastering hell let loose vietnam boat tactics separates squads that cap objectives from those that feed the river. With both factions fielding heavily armed patrol boats on the network of waterways, controlling the rivers gives you a mobile flank that most infantry never expects. This guide breaks down how to coordinate boat insertions with tank support, mortar fire, and recon overwatch to turn water routes into decisive push vectors.

The key insight is that boats are not just transport — they are fire support platforms that can suppress shoreline defenders while your infantry establishes a beachhead. When you combine a well-timed boat assault with a tank pushing the main road and mortars hammering the point, you create a three-axis attack that overloads any defense. Let's get into the specifics of making riverine operations work in Hell Let Loose: Vietnam.

Riverine Assault Planning and Boat Deployment

The foundation of any successful river operation starts before the engine turns over. Boat squads need to coordinate with the Commander and other unit leaders to ensure their insertion point aligns with the overall attack plan. According to the official game page, both factions use armed patrol boats on river networks, which means you will face enemy watercraft and shoreline ambushes.

Choosing Insertion Points

Not every riverbank is a good landing zone. You want a spot that offers natural cover for unloading troops, a short sprint to the nearest trench or treeline, and a line of sight that does not expose your squad to enemy armor. Look for bends in the river where the current slows and the bank provides a slight elevation advantage. Avoid straight stretches where a single machine gunner can enfilade your entire squad as they disembark.

Boat Spawn Coordination

Your squad leader should place an outpost near the river before the boat arrives, giving you a fallback spawn if the landing goes wrong. This also lets you regroup quickly if the boat takes damage and sinks. Coordinate with the Commander to drop supplies nearby so your Support player can build a garrison after the beachhead is secured.

The table above shows that each insertion type demands different support. A feint works best when you have a fast boat and a crew willing to draw fire, while a direct assault needs the full combined-arms treatment.

Tank Strategy for Shoreline Support

Tanks are your heaviest hammer for riverine operations, but they cannot drive into the water. Instead, armor units need to position themselves on roads that run parallel to the river, providing overwatch fire while infantry crosses. This creates a deadly crossfire where defenders must choose between exposing themselves to the tank or to the boat's mounted guns.

Armor Positioning Grid

The best tank positions are slightly elevated spots with a clear sightline to the landing zone and the enemy's likely reinforcement routes. You want to be far enough back that enemy anti-tank teams cannot easily sneak up on you, but close enough that your main gun can suppress bunkers and machine gun nests. A hull-down position behind a low rise is ideal because it exposes only your turret.

Coordinating Fire With Boat Landings

Timing is everything. The tank should open fire 30 seconds before the boat reaches the shore, targeting known defensive positions and forcing defenders into cover. This suppression window lets the boat close the distance without taking heavy fire. Once the infantry is on the ground, the tank shifts to engaging any enemy armor or vehicles that threaten the beachhead.

Tank RolePrimary TargetSecondary TargetPositioning

BreakthroughReinforcementsDefensive structuresClose to landing zone

According to community reports from the open beta, tank crews that communicated with boat squads were significantly more effective than those operating independently. The rifle squad guide explains how infantry units can mark targets for armor, which is essential for this coordination.

Mortar Tactics for Beachhead Suppression

Mortars are the artillery backbone of a riverine assault, providing indirect fire that keeps defenders' heads down while your infantry establishes a foothold. Unlike the tank, mortars can be positioned well behind the front line, safe from direct fire, and can drop shells on the landing zone with deadly precision.

Pre-Planned Fire Missions

Before the boat launches, the mortar squad should zero in on three or four key targets: the main defensive trench, the most likely reinforcement route, and any known machine gun positions. By pre-plotting these targets, you can drop smoke and high-explosive rounds within seconds of the landing, rather than waiting for a spotter to adjust fire.

Smoke vs High-Explosive

The mix of smoke and HE rounds is critical. Smoke screens the boat's approach and the infantry's advance, while HE rounds kill or suppress defenders who are trying to shoot through the smoke. A common pattern is two smoke rounds followed by three HE rounds, repeated until the beachhead is secure. The mortar observer role is essential here, as they adjust fire based on what they see from the front line.

Fire Mission TypeRound MixDurationPurpose

Defensive Suppression3 HE, 1 smoke90 secondsPin defenders in trenches
Reinforcement Denial4 HEContinuousBlock enemy reinforcements

The mortar observer guide covers the communication protocols needed to call these missions effectively. Without a dedicated observer, your mortar fire will be slow and inaccurate, wasting precious ammunition during the critical landing window.

Recon and Sniper Strategy for River Overwatch

Recon squads play a force multiplier role in riverine operations, using their scoped rifles and binoculars to spot enemy positions before the main force commits. A well-positioned sniper can eliminate the boat's machine gunner or the tank's commander, crippling the defense before the assault even begins.

Spotter-Sniper Coordination

The spotter's primary job is to mark high-value targets for the sniper and relay information to the Commander. This includes enemy tank positions, mortar locations, and reinforcement routes. The sniper then engages targets of opportunity, prioritizing enemy officers, machine gunners, and anyone carrying a rocket launcher. This combination of information gathering and precision fire makes the recon squad the eyes of the entire operation.

Overwatch Positions

The best overwatch positions are on high ground overlooking the river, with a clear view of both the landing zone and the enemy's likely response routes. A position on a hill across the river is ideal because it gives you a plunging fire angle that is difficult for defenders to locate. However, you need to be careful about your escape route, as a compromised recon squad is a dead recon squad.

The spotter guide explains how to mark targets for mortar and artillery support, which is essential for coordinating with the fire missions described above. A good recon squad can effectively direct the entire battle from their overwatch position.

Push Strategy: Combining All Assets

The final piece of the puzzle is the overall push strategy that ties boats, tanks, mortars, and recon into a single, coordinated assault. This is where the Commander's role becomes critical, as they must sequence the attack so that each asset arrives at the right moment.

The Three-Phase Assault

A successful riverine push follows a three-phase pattern. Phase one is recon and preparation, where the spotter marks targets and the mortar squad zeroes in. Phase two is suppression and movement, where the tank opens fire, mortars drop smoke, and the boat begins its approach. Phase three is landing and consolidation, where infantry secures the beachhead, builds a garrison, and begins pushing toward the objective.

Timing the Main Push

The boat assault should be a diversion or a supporting attack, not the main effort. While the defenders are focused on the river, your main force should be pushing from another direction, ideally with armor support. This creates a dilemma for the enemy: if they reinforce the river, the main push breaks through; if they ignore the river, the boat squad caps the point from behind.

Frequently Asked Questions

What is the best boat for riverine assaults?

The heavily armed patrol boats available to both factions are the best choice for assault operations because they provide mounted guns that can suppress defenders during the approach. While transport boats are faster, they leave your squad completely exposed. Always prioritize the armed variant for contested landings.

How do I coordinate tank support with a boat landing?

Coordinate with the tank commander before the assault begins, agreeing on a fire plan that targets known defensive positions. The tank should open fire about 30 seconds before the boat reaches shore, then shift to engaging enemy armor once the infantry is on the ground. Clear communication is essential.

What role does the mortar squad play in a riverine assault?

The mortar squad provides indirect fire that suppresses defenders and screens the landing with smoke. They should pre-plot fire missions on key targets and adjust based on spotter reports. A good mortar team can keep defenders pinned while your infantry establishes a beachhead.

How can recon help with boat tactics?

Recon squads spot enemy positions before the assault, mark targets for mortars and tanks, and eliminate high-value defenders like machine gunners and officers. Their overwatch position on high ground gives them a clear view of the landing zone and enemy reinforcement routes.

What is the most common mistake in riverine assaults?

The most common mistake is treating the boat as simple transport rather than a fire support platform. Squads that rush to shore without suppressing defenders get cut down. Always coordinate with tanks, mortars, and recon before committing to a landing.
