War Command's first start came on 7 June 2013 in a seven-furlong maiden race at Leopardstown, which he won by a neck from the pre-race favourite Intensified. Eleven days later War Command travelled to Royal Ascot for the Coventry Stakes. He was an outsider for the race and started at the price of 20/1, with his trained Aidan O'Brien also having two more fancied runners in the colts Stubbs and Sir John Hawkins. War Command's jockey Seamie Heffernan, held him up near the rear of the field in the early stages of the race, before moving closer to the leaders with two furlongs left to run. He took the lead with over one furlong before the finish and pulled clear to win by six lengths from Parbold. War Command's stable-mate Sir John Hawkins finished three quarters of a length behind Parbold in third place. After the performance he was priced as short as 5/1 for the 2014 running of the 2000 Guineas Stakes. War Command then stepped up to Group 1 level for the Phoenix Stakes at The Curragh. He started as the 2/5 favourite of the field of five. Ridden by Joseph O'Brien, he could only manage to finish third, one length behind winner Sudirman. War Command returned to The Curragh on 24 August for the Futurity Stakes. After again starting as an odds-on favourite he took the lead inside the final furlong and pulled clear to win by three lengths from Mustajeeb. On 12 October, War Command was sent back to England to contest Britain's most prestigious two-year-old race, the Dewhurst Stakes over seven furlongs at Newmarket Racecourse. Ridden by Joseph O'Brien, he started the 10/11 favourite against a field which included the July Stakes winner Anjaal and the Champagne Stakes winner Outstrip. He raced behind the leaders before taking the lead a furlong from the finish and winning by one and a quarter lengths from the 20/1 outsider Cable Bay. In November, War Command was narrowly defeated by Kingston Hill in the voting for Champion Two-year-old Colt at the Cartier Racing Awards.
2014: Three-year-old season
War Command began his three year old season in the 2000 Guineas in which he was ridden by Ryan Moore. He entered the race at odds of 8/1 and could only finish ninth of the fourteen runners five and a quarter lengths behind 40/1 winner, Night of Thunder. His next engagement was the St James's Palace Stakes at Royal Ascot, in which he finished fourth behind Kingman, Night of Thunder and Outstrip. In July he was matched against older horses for the first time in the Eclipse Stakes over ten furlong at Sandown Park Racecourse. Starting at odds of 8/1 he finished seventh of the nine runners behind the five-year-old Mukhadram.
