Players generally don't have practical knowledge of military or skirmish tactics, yet are expected to be able to play such encounters with a modicum of intelligence. Fortunately games tend to have more or less abstracted rules that let you just announce an intention to damage a target and then roll dice to see if your character can do it. But adding some roleplaying into a combat encounter can be additional fun and give you the chance to try out some unconventional tactics in a situation which isn't going to be dangerous as it would be in real life.

Rather than just say, "I hit the goblin with my sword", you can try, "I point behind the goblin and yell 'What's that?!', then use the end of my sword to tip the oil lamp hanging on the wall on to the pile of straw bedding." Or something to that effect. Much more interesting!
