Obama has to invest more in soldiers, families, veterans and must improve healthcare. A lot of people are waiting to see if he keeps the promises he made on this issue during the campaign. The military also should be restructured... There is too much dependence on National Guard and Reserve units (something Clinton implemented).
Of course one way to relieve the strain on the military is to have a completely different foreign policy approach to begin with.
I would also like to see the Obama Administration re-investigate the numerous suspicious death cases of soldiers overseas... But I know that isn't going to happen. The deaths of these soldiers are not priorities and never will be priorities for suits in Washington DC. I really don't think any of those people give a damn about individual cases.
But improving overall conditions will improve quality of life, reduce divorces (due to excessive deployments), reduce family violence, reduce suicides, improve the quality of housing and health services.
