What Is an Anti-Tank Guided Missile (ATGM)? Tank Killers Explained

# What Is an Anti-Tank Guided Missile (ATGM)? Tank Killers Explained

Quick answer: An anti-tank guided missile (ATGM) is a missile designed to kill armored vehicles. A single soldier with an ATGM can destroy a tank costing $10 million from 2–8 km away. ATGMs changed warfare by making tanks vulnerable to infantry.

Three Generations of ATGMs

Generation	Guidance	Soldier Has To…	Example
1st gen	Wire-guided, manual (MCLOS)	Steer with joystick (very hard)	AT-3 Sagger
2nd gen	Wire/laser, semi-auto (SACLOS)	Keep target in crosshairs	TOW, Konkurs, Milan
3rd gen	Fire-and-forget (IIR/laser)	Lock, shoot, run	Javelin, Spike, OMTAS

Modern soldiers love 3rd-gen because after firing, they can run away before the tank’s gunner spots them. With older missiles, you had to keep aiming for 10–20 seconds while the missile flew — and you became an easy target.

How an ATGM Defeats Heavy Tank Armor

Tank armor is up to 1 meter thick of steel-equivalent on the front. How does a 10 kg missile defeat that? Three tricks:

1. HEAT (High-Explosive Anti-Tank)

A shaped explosive charge focuses energy into a thin jet of molten metal that pierces armor like a needle through butter. Most ATGMs use HEAT.

2. Tandem Warhead

Modern tanks have reactive armor (ERA) — small explosive blocks that fire outward to disrupt incoming jets. Tandem warheads have two charges: a small one to detonate the ERA, and a main one to penetrate the real armor behind.

3. Top-Attack

The top of a tank’s turret is much thinner (~50 mm) than the front. Modern ATGMs like Javelin climb upward and dive down onto the roof for an instant kill.

Famous ATGMs

Name	Country	Range	Generation
FGM-148 Javelin	USA	2.5–4.5 km	3rd, top-attack
9M133 Kornet	Russia	5–10 km	2nd (SACLOS laser)
Spike	Israel	2.5–30 km	3rd, multi-mode
Milan / MMP	France	2 / 4 km	2nd / 3rd
TOW-2	USA	3.75 km	2nd, wire
HJ-12 Red Arrow	China	2 km	3rd
OMTAS	Türkiye	4 km	3rd, fire-and-forget
UMTAS / L-UMTAS	Türkiye	8 km	helicopter/drone-launched

ATGMs in Recent Wars

2014– Donbas war: Russian-supplied ATGMs hit Ukrainian armor.
2020 Karabakh war: Bayraktar TB2 + MAM-L / MAM-T destroyed Armenian tanks (these are precision munitions, related to ATGM family).
2022+ Russia–Ukraine war: Javelin and NLAW became famous, destroying Russian armored columns. Photos of burned-out T-72s with neat round penetration holes shocked the world.
2023+ Middle East: Spike, TOW, and Kornet used widely.

The Javelin’s nickname in Ukraine became “Saint Javelin” — a viral image of a religious icon holding the missile.

The “Tank Is Dead” Debate

After 2022, many analysts said tanks are obsolete because cheap ATGMs and drones kill them so easily. Tank designers responded with:

APS (Active Protection Systems) — like Trophy or Iron Fist that shoot incoming missiles down
Slat armor / cages — disrupt shaped-charge jets
Stealthier shapes

The truth: tanks aren’t dead, but unsupported tanks (no infantry, no drones, no air cover) are. Modern combined-arms warfare is needed to keep them alive.

How a Javelin Works (Simple)

1. Soldier opens the launcher, sees target through thermal sight.
2. Pulls trigger; missile locks onto target’s shape (not heat).
3. Soldier presses fire. Soft launch ejects the missile gently from the tube (no back-blast inside a room).
4. Missile motor ignites once safely away.
5. Missile climbs to ~150 m, then dives.
6. Penetrates the thin top armor.
7. Tank’s ammunition cooks off in a “Jack-in-the-box” turret toss.

Soldier was already running away by step 4.
