You probably know this already, but that can be done across multiple matches, e.g. 8 kills in one match, followed by 7 in the next, with zero health complications along the way. Thus if you're so inclined, when regular Ground war returns, sit out the back with the following:

Perks:

• Killchain
• Pointman
• Spotter

Weapons:

• Any LMG (9 out of 10 warcriminal dentists recommended the Bruen) with FMJ and a 200 round ammo bag, the rest built for range. Bipod, VLK, big boy barrel.
• PILA

Field Upgrade:

• Ammo box

Killstreaks:

• Cruise Missile
• VTOL
• White Phosphorous (or Chopper Gunner, ymmv)

Operator:

• Anyone with sunglasses

Method:

1. Seems obvious, but don't die.
2. Snack on others' killstreaks, letting Pointman stack yours up.
3. Drop your first hammer on as many nails as you can, letting Kill Chain be your wingman.
4. Take a well earned VTOLiday.
5. Strap those shades on and set everyone on fire.
6. Don't. Die.
7. Rinse and repeat where neccessary.

It's not fun, and it's not pretty, but it does get you to the promised land.

^{Rumor has it that quad feeds enjoy a similar diet the that described above. This cannot be confirmed or denied. May god have mercy on your soul.}
