Yes they do.
The original Viet Cong manuals (well in reality often drawn on cardboard or wood) showed how to aim RPG's for example, and then were updated to show in pictorial form how to aim such weapons at helicopters in differing flight regimes (the method used to this day, and no this is not a beadwindow thingy).
I also suspect that the IRA updated their own ways of firing projectile weapons, after it was realised that firing one from the inside of an Austin mini had its drawbacks
