"When you see a countryman in trouble, and you try to help him, is there anything expected from him?"
As some of the other people have pointed out, you're foisting a moral burden on the other player that he did not ask for. He might not even realise that you are trying to help him, as he will have his hands full in the fight. He might be spitting blood that someone did not help him earlier. Or he might be an ultra-humanite who has the enemy right where he wants them.
There have been times where I have been hard-pressed, cursing that no-one is coming to help me, but I always try to bear in mind that perhaps someone *is* trying to help me, or perhaps I am beyond help, or the other players are occupied, and in any case why should they help me in particular? Other people might be in danger. Emergency service workers are trained so that, when confronted with a dangerous situation, they should not become casualties themselves in their eagerness to help.
There is something to be said for diving at the enemy in the hope of putting them off, although eventually the surprise factor will wear off, and some players might not even notice that they are being buzzed. My greatest fear nowadays is the new Spitfire 16 player on my tail, because he is unlikely to check behind him for a counter-pursuing enemy and he will probably out-turn me and spray me down. My other greatest fear is any Corsair above me.
