Military leaders have said that they can live with an active duty Army of 490,000 — bolstered by nearly 500,000 soldiers in the National Guard and Reserves — as long as Congress provides enough funding to support that troop level. Gen. Mark Milley, the Army chief of staff, said last month that he is comfortable with a 1 million-soldier Army, and would welcome a larger force, only if Congress provides the money to maintain troop readiness.
