I think the RPG7 guide on page 1 still applies in 1.63.
RPG-18
Missile explodes in air at around 450m, takes around 4 seconds to reach 400m, so speed looks to be 100m/sec, very slow compared to M136 which takes 1 sec to reach 400m.

It's 115 m/s.
The RPG 18, other than the RGP-7, has only a one stage rocket motor that completely burns up during the time the rocket is in the launch tube. That makes the effective range of the rocket very low (100% hit chance at around 200 meters).
Actually, Arma 2 and Arma 3 have a rather sophisticated model for the missiles. The projectile is generated at the muzzle at the speed given as initSpeed in the ammo.cfg. This simulates the time/acceleration within the launch tube. Once created, after initTime from ammo.cfg, the second stage motor sets in, propelling the missile/rocket at a thrust given in the ammo config for a certain amount of burn time. The projectile accelerates up to the given maximum speed, with air friction taken into account.
RPG-7's, for example, have a two-stage rocket. The first burn accelerates the grenade from the launch tube to 115 m/s muzzle velocity, then after 0.1 seconds, the second stage motor sets in, propelling the rocket with a thrust of 280 for one second, at which time the motor burns our.
The effect is that the RPG-7 drops a bit at the start, then picks up speed as it flies and finally starts to drop again when the motor burned out. Max speed is almost 300 m/s.
Not AT/AA, but I think some rifle scopes are an enigma, too.
KSVK
I ranged the triangles since they're a point of reference, all other ranges are in between (700m is half way in between 600m marker and 800m, for example)
