I can only guess at how long the full return fire process takes, but you only need to be pointing a javelin AT at the tank, it will do the rest. You can be sprinting away pretty much as you launch and get 50 meters away. Safe? Hell no, but it's not as bad as the "2 seconds" comment makes it out to be.
NLAW has 1000m range. AT4 and Panzerfaust3 has 300m range.
If you are using an NLAW and the enemy tank has line of sight 3000 meters away, you are outgunned, outranged, and outmaneuvered and almost certainly will lose.
The tank has 40+ shots with a firing rate every 4 seconds. Javelin is a 50LB weapon that is single shot, so a miss (due to thermal smoke grenades / flares) is a critical mistake that will kill you.
Running away at 3km/hr only delays the inevitable, as the tank travels 50km/hr to close the distance with you... And had far more shots to invoke suppressing fire to scare you from running away effectively.

The advanced weapons help, but a tank is a tank. It's faster than you, has more range than any weapon you can carry, is almost always decked out with the best night vision optics, has more bullets, bigger bullets, and armor to negate most of your weapons.
At best the advanced missiles even the odds. I'm not sure if I'd call it an advantage though, because of the single shot nature / long reload times of missiles / recoilless rifles, especially compared to tank guns.
> In contrast, the Javelin you launch will take 12 seconds before it hits the tank at that range.
What's the latency for the turret to pivot to the target angle? I suppose it's pretty fast but let's say in worst case 180deg? How long does that take? 1s? 10s?
