While most US war veterans tend to be supportive of their country's military operations abroad, some have been voicing their opposition to any escalation.
For weeks, Washington has been debating whether to send more troops to Afghanistan but a growing number of veterans are lobbying US politicians against a new war strategy for Afghanistan that Barack Obama, the US president, is expected to deliver on Tuesday.
While the budget for Obama's military plan would need final approval from the US congress, many veterans are hoping for an outcome that will cost fewer lives and mean fewer men going to war.
