Firefighters get full body pressure suits with an independent oxygen source that isolates them from all environmental hazards. They are also strength enhancing and heavily armored, making them tough to kill. Their signature impulse cannons, the IFEX 6000 Model, load 76mm shells of various payload. Each firefighter also carries a total of five fireaxes hanging from their back, the reason being that each one's head is loaded with high explosive, for when blunt instruments just won't do. The remote detonation is also very useful.

The paramedic naturally carries his medical supplies which he can use to patch up anyone within moments, but he also humps extra ammunition and mission critical equipment, as well as whatever other guff he wants. Medics are all expertly trained in hand to hand combat, but why would you want to punch someone when you can hose em', because medics are also fantastic at using small, light weapons, like hand lasers and submachine guns.
