Republican presidential candidate also vowed to increase military spending to revive the ''depleted" US forces if he assumed office
Republican presidential candidate Donald Trump promised to expand US military and outline a plan to beat Islamic State within a month of assuming office.
Trump said he would increase military spending, number of soldiers, aircraft and warships to revive the "depleted" US forces.
Speaking in Philadelphia, the billionaire gave a detailed plan of increasing the US military. The US army would have 540,000 troops, the air force would have at least 1.200 fighter aircraft and the navy would have 350 surface ships and submarines, the AFP reported.
About his plans to tackle the IS, Trump said, "Immediately after taking office, I will ask my generals to present to me a plan within 30 days to defeat and destroy IS."
Trump's 30-day timeframe to beat the IS was, however, assailed by a retired army general.
"I had to ask myself, what the hell does he think we've been trying to do for the last 14 years in terms of al Qaeda?" Retired Army Lt. Gen. Mark Hertling told CNN.
Trump, meanwhile, also took a swipe at his opponent Hillary Clinton, calling her "trigger happy" because of her "legacy in Iraq, Libya and Syria" that has "produced only turmoil and suffering and death".
With the election campaign having entered the homestretch, Trump also urged NATO (North Atlantic Treaty Organisation) to spend 2 per cent of its national income on defence.
