Final answer:
The question about what the three AWOLS take on the bus does not directly align with the given textual references, which relate to various historical and situational contexts, including the freedom riders and groups of soldiers or agents, without mentioning specific items being taken onto a bus.
Step-by-step explanation:
The three AWOLS mentioned do not take anything specifically with them on the bus as described in the provided texts; rather, the texts refer to historical events and situations involving groups of individuals: attacks on the freedom riders in Anniston, Alabama; prisoners being given a chance to escape at sea; a scene depicting a diverse militia; pondering the use of an omnibus for a life-crew; soldiers in groups of three or four with black uniforms under their coats; and harsh treatment of people crossing deserts portrayed through a divisive enforcement agent's nightmare.
Therefore, the question as presented does not align with the references given and seems to be based on a different context that is not provided in the excerpts. The information suggests a mix of historical social studies topics rather than a literal interpretation of individuals taking items onto a bus.
