From Crisis of Conscience, 2004 edition:
Consider this case that came up for discussion and decision by the Governing Body. One of Jehovah’s Witnesses, driving a truck for the Coca-Cola Company, had as his route a large military base where numerous deliveries were made. The question: Could he do this and remain a member in good standing or is this a disfellowshiping offense?
[...]the majority of the Body decided that this work was not acceptable and that the man would have to obtain another route to remain in good standing.
Even indirect 'support' was unacceptable to the GB, when it came to the rank and file.
