new to arma 2 few questions

[xellos]

hello all im new to arma 2 and have a few questions.

1 i was playing a mission the other day and i walked in a building up the stairs.
there was an ai enemy sitting there facing the wall so i shot him.
then i got tru the door to an other room there was another ai enemy facing the other way doing nothing.

but he must have heard the shots so i shot him to.
and 2 more enemys.

what im trying to say is is it a bug that the ai sometimes just sit stil?

2 if my team says enemy 1 O clock is it mine 1 o clock or his?

3 whats the biggest diffrence between the dificulty settings?
