Thermal Clips

Modern infantry weapons are micro-scaled mass accelerators, using mass-reducing fields and magnetic force to propel miniature slugs to lethal speeds. Nearly every gun on the battlefield is laden with features, from targeting auto-assists to projectile shavers that can generate thousands of rounds of ammunition from a small, internal block of metal.

It was long though that personal weapons had plateaued in performance, but the geth proved all theories wrong. Mathematically reviewing their combat logs, the geth found that in an age of kinetic barriers, most rounds down-range the fastest. But combatants were forced to deliberately shoot slower to manage waste heat or pause as their weapons vented.

To eliminate this inefficiency, the geth adopted detachable heat sinks known as thermal clips, While organic arms manufacturers were initially doubtful this would produce a net gain, a well-trained soldier can eject and swap thermal clips in under a second. Faced with superior enemy firepower, organic armies soon followed the geth's lead and today's battlefields are littered with these thermal clips.
