Based off of the TFA version, but vastly superior and designed for team base battles and PvE scenarios using ArcCW weapons:

Item Thrower
Class: What would you call this?
Year: Whatever year the ammo was manufactured, I guess
Mechanism: Your muscles
Ammo type: (varying)
Country: ?????
Manufacturer: Who reads this...?

Description: "A support 'weapon' which can be used to throw ammo of your choice as well as healing items.
Can also be used as a makeshift grenade, by throwing an ammo box at an opponent and then shooting it.
THROWING A HEALING ITEM WILL DAMAGE YOURSELF. USE AT OWN RISK."

Function: Throws an ammo box or healthkit/healthvial/suitbattery based on which ammo type was chosen.

Notes: Has 13 exclusive ammo types and 3 exclusive perks. Using Health Vial will damage yourself for 10, using it with Larger Package will damage self for 25, using Suit Battery will damage your suit for 15 and is only usable with 15 suit-HP or more. All ammo types and perks are like Cowboy Style in that you will immediately get them upon spawn and will not run out, even with free attachments and attachment locking off. All ammo types affected by Larger Package will throw the large versions of the ammo boxes. Using Health Vial without the minimum amount of health will kill you. Right-clicking will simply drop it infront of you instead of violently chucking it.

Attachment Slots: Ammo Type, Perk

Ammo Types: Airsoft (BB Pellets), Carbine (smg1), Magnum (357), Pistol (pistol), Rifle (ar2), Rifle Grenade (smg1_grenade), Shotgun (buckshot), Sniper (SniperPenetratedRound), Grenade (grenade), Claymore (slam), Rocket (rpg_round), Health Vial (Self-damage), Suit Battery (Self-damage to Suit)

Perks: Strong Arm (Thrown item goes 40% further), Larger Package (All applicable ammo types will use the large ammo variants but cost more, Health Vial will throw a health kit instead), Nimble Hand (Pull out another item after throwing 50% faster)
