In reality, almost any exploding projectile, even a small under-barrel grenade, is equipped with a fuse delay for the safety of the shooter. In the game, a shell or missile can explode as soon as it leaves the barrel. You can adjust the firing distance, but the AI ​​has difficulty identifying obstacles in the way, plus it does not take into account the launch deviation of the missile. For this reason, I blew up an entire lance several times with a large missile launcher.

Either precise adjustment of the fuse is needed, or it should automatically set fuse delay at the restricted close firing distance.
