My gaming group consists of 5 players. Most of which are 1st generation players (meaning 1st edition) and one 3rd generation player. Yet despite all of the experience these guys have, they seem to lack any idea of tactics in combat. All too often they become static, don't move around, don't utilize their feats, and hardly ever use other combat options like bull rushing, disarming and (the gods forbid) grappling. I have gone over tactics with the group before yet it just doesn't seem to sink in. They need to use cover, and the space that is around them.
I use the monsters to the extent of their abilities. I use their abilities to rake, grapple, bull rush, bite, and to exploit their weaknesses. The more intelligent the monster I am player, the more likely it'll go after the lightly armoured, or the most dangerous. Does anyone else have this problem? I have used my gameplay as an example, I have spoken with the group directly, and I have gone as far as forwarding discussions of combat rules that appear on the D&D website, and from threads on EN world.
How do you handle this problem? If it exists in your group I mean.
