 CONT: On the combat drop from the Sulaco, Hicks falls asleep.  However, when Hudson is giving his speech to Ripley, Hicks is sat  behind Hudson and is wide awake, but when it cuts back to him he is  asleep again. Then in the next shot he is still awake and then he  goes back to being asleep, which then corresponds to Apone saying,  "Somebody, wake up Hicks".
