Starfinder Enhanced pg. 75
When you make a full attack while wielding two one-handed melee weapons, two small arms, or a small arm and a one-handed melee weapon, you can make two attacks with one weapon and two attacks with the second weapon in any order. You take a –6 penalty to these attacks instead of a –4 penalty. You must have the soldier’s onslaught class ability to take this gear boost.
