Krogan are common soldiers that are seen around the galaxy. They are armed with a variety of weapons and are capable of charging and doing massive damage, both with their weapons, and with their powerful melee attacks. Krogan are used as shock troops by many Mercenary bands and organizations for various tasks across the galaxy.
In addition to being used by pirate and mercenary groups, Saren, who had found a cure for the genophage, began breeding an army of krogan to supplement his geth forces. Krogan are seen on many worlds being used by both mercenary and Saren's forces. When dealing with that latter, where krogan will be found, geth will usually be in the same area as well, or at least nearby.
Like all krogan enemies, if they aren't killed while in the air, or by ammunition/grenades that can destroy targets upon death (like incendiary, toxic, and high explosive), then they will regenerate once before going down for good, so make sure to put them down for good.
