I've never run across an LMG Gunner Support Kit. The SAW/LMG gunner usually carries all of the stuff they need to keep the LMG going. The spare barrel, extra ammunition, small spare parts kit, cleaning kit. They have to carry all of that over top of their normal issue equipment.

There is an MMG Support Kit that the is carried between the gunner and assistant. There would be a spare barrel, possibly 2 carried (heat resistant mites and pad), spare parts kit, cleaning kit, extra ammunition. There is also a sustained fire kit which can also be carried, which is the tripod and gunner sight as well as the rest of the kit carried, this would be used in a defensive position or a sustained fire position only. They have to carry all of this over and above their regular kit. The assistant would also carry their personal weapon (most often a rifle of some kind), the MMG gunner, the MMG is there's.

There is an HMG Kit as well, this again is usually a 3 person team, gunner assistant #1 and #2. There is a spare barrel, tripod, extra ammunition, spare parts kit. This would rarely be employed in the ground role, but could be if needed.

Spare parts kit; normally are an extra bolt, extractor, springs, firing pin, gas plug, trigger, screws, pins, extra blade sights, this sort of thing. The kits would include anything that could break out in the field that could prevent the weapon the functioning, since they would not have access to an gunsmith during combat.

Cleaning kit; pipe cleaners, tools needed to disassemble, clearing plug, lubricant, cleaning tools (scrapers for bore, gas plug that sort of thing), 3 or 4 piece rods, bore brushes, cleaning patches (lots of these), if the weapon requires the setting of head spacing and timing, there are tools for that (usually the older M2HB without a modernization kit).
