They aren't defending a city or evacuating civilians here. As soon as they noticed they are fighting a titan with the intelligence of a human, they should have just given up and decided to stay alive instead of heedlessly attacking.
I'm pretty sure Eren has killed just as many titans as these veterans. He killed a score of them while in his titan form. Besides, that doesn't even have anything to do with what I said: I said Eren should have been obsessed with killing titans, after he watched them eat his mother. But there's no sign of that anymore. Now he behaved like any normal new soldier would. I preferred his old self that was stupidly eager to massacre giants.
