It's not uncommon for sailors in the U.S. Navy to express a culture that treats human relationships like business deals. But that prevailing culture actually is an honest and ugly reflection of capitalist culture.
A good number of relationships in the Navy, as in other domains of capitalism, revolve around money. Relationships are just a means intended to advance careers, to earn more money, or to provide better living quarters.
Much of this behavior is encouraged by the way the bosses set up their pay allowances. It's common for junior sailors to get married in the military primarily, and a lot of time solely, because the military offers additional Basic Housing Allowance (BAH). This means married sailors can live off the ship or out of the barracks, but single sailors have to stay aboard. Moreover, BAH is big chunk of cash; it easily doubles a junior sailor's salary.
This is a gigantic monetary incentive for sailors to marry just for a pay raise. It's understandable why sailors do it. The military shafts enlisted personnel all the time. The U.S. military budget was over $700 billion dollars in 2011, which means the U.S. spent more on its military than the next 13 nations combined in 2011. Yet enlisted junior sailors have to get married in order to earn enough money to live off the ship.
A problem arises when sailors begin behaving with a capitalist mentality that relationships with people are reduced to credit or debit payments, like any other money-making enterprise. This sort of degenerate behavior stems from cultural norms created by capitalism, where even loved ones are bought and sold. We have to recognize that capitalism is the culprit that is encouraging us to objectify people.
Another consequence of capitalist culture in the military is the implicit permission for sailors to treat women outside the US as sex commodities. Thailand is known to have the worst sex trafficking problems in the world, and it is also a frequent port stop for the Navy. Prostitutes are bought by some sailors as though they were buying any other good at a grocery store. In the Navy there is one training after another about preventing rape of shipmates, since rape in the U.S. military is known to be rampant. (As we go to press, it had been reported that there were 26,000 cases of unreported sexual assaults in the military last year, 35% more than the year before). But there is not much said about participating in prostitution in other countries and exploiting those women. If anything is said at all, it is usually a selfish concern about catching sexually transmitted diseases.
Some people may think that these degrading and exploitative values are exclusive to the military, but really these values are a direct and overt expression of what's permitted and encouraged throughout all of capitalism. Capitalists would love for all workers to think and act in accordance with military culture, since it's a culture that preserves their oppressive system.
Deployment already places pressure on sailors to stay connected with their families and loved ones. Respecting people and fidelity in relationships keeps sailors thinking clearly about how to fight back against the bosses that are oppressing them, their families and all their shipmates. Sailors, just like every other worker in the world, need to fight for communism. We don't need capitalism and its exploitation of women and we don't need the capitalists' filthy culture.

In Oakland, we found that the strategy that suited capital was to divide and scatter the movement among various demonstrations. We were able to go to two of them. One was a demonstration of high school students at the Federal Building against deportations. The main demonstration in downtown Oakland, much smaller than last year, included union members from SEIU as well as workers on strike from the Mi Pueblo chain of grocery stores. At both of these demonstrations we found that workers were very receptive to Red Flag's message of "Production for need, not for profit! Fight for a world without borders, wage slavery, racism, sexism, and imperialist wars," which was in sharp contrast with the reformist messages of the protests.
