Assistant Kits. Suggestions please

[Matt W]

It occurs to me that we don't see the "other half" of those teams who operate some of the heavier weapons

For example, it is possible for an individual PC to be issued something like the MAG-58 machine gun with 3 belts of ammo. NOBODY in the real world sends this guy out on his own. Someone should be with this guy and carrying another 4 or 5 belts of ammo, a couple of spare barrels and the tripod.

What would you put in the "assistant LMG gunner kit"?

Similarly,real-world marksmen/snipers rarely work alone. There's usually a second person, a "spotter", with spare ammo, starlight scope and a laser range finder. Their job is to support and protect the sniper

What would you put in a "spotter" kit ?

What would you put in something like the "assistant missile operator kit"? OR "assistant rocket launcher operator kit"?

I'm trying to decide between 2 options

1. an Individual Basic Load for these kits (like the already-existing Doctor's Assistant issue). To include weapons
2. A literal "kit bag" that anyone can pick up and use if, for example, the sniper needs support.

Opinions and suggestions are welcomed
