Top attack delivers a plasma jet to the thinner armor on the top-deck.. it won’t bounce off the front of the tank. It’s a great equalizer when you don’t have a 30 mm Gatling on a tactical air support fixed wing or helicopter.
The war will be over when Ukraine runs out of rounds.

Javelin is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a
top-attack flight profile against armored vehicles (attacking the top armor, which is generally thinner), but can also take a direct-attack mode for use against buildings, targets inside the minimum top-attack engagement range, and targets under obstructions. The missile also has the ability to engage helicopters in the direct attack mode.
[7]
It can reach a peak altitude of 150 m (490 ft) in top-attack mode and 60 m (200 ft) in direct-fire mode. It is equipped with an
imaging infrared seeker. The
tandem warhead is fitted with two
shaped charges: a precursor warhead to detonate any explosive
reactive armor and a primary warhead to penetrate base armor.

The Javelin missile's tandem warhead is a
HEAT type.
[7] This round utilizes an explosive
shaped charge to create a stream of
superplastically deformed metal formed from trumpet-shaped metallic liners. The result is a narrow high velocity particle stream that can penetrate armor.
The Javelin counters the advent of explosive reactive armor (
ERA). ERA boxes or tiles lying over a vehicle's main armor explode when struck by a warhead. This explosion does not harm the vehicle's main armor, but causes steel panels to fly across the path of a HEAT round's narrow particle stream, disrupting its focus and leaving it unable to cut through the main armor. The Javelin uses two shaped-charge warheads in tandem. The weak, smaller diameter HEAT precursor charge detonates the ERA thus clearing the way for the much larger diameter HEAT warhead, which then penetrates the target's primary armor.
