The US Army's chief of staff has urged a quick resolution to the budget row that has led to non-essential government services being closed - known as a 'shutdown' - warning that it was significantly harming the Army's day-to-day operations.
General Ray Odierno told Reuters: "It is going to be difficult for us to do anything.
"We won't be doing training like we normally would, we won't be travelling, we won't be doing the co-ordination necessary, only mission-essential tasks."
The US shutdown is but a precursor to a much bigger problem - in a couple of weeks the government, shutdown or not, will run out of cash.
Landmarks across the US have closed as the Congress failed to reach a deal over the budget.
