KABUL (Reuters) - The Afghan soldier who killed U.S. Major General Harold Greene had spent three years in the army before he squeezed off two to three bursts of gunfire from a first-floor window at a senior military delegation in Kabul, officials said on Wednesday.

As details emerged about Tuesday's attack at a military complex in the Afghan capital, a picture was forming of a rogue Afghan soldier who may have been difficult to spot before he killed Greene and wounded 14 coalition troops.
