Weapons – Here are the best weapons for Commando to use, from your primary to your sidearm.

Primary	Kightsbridge: Provides you with high ammo capacity. SCAR EIR: Equipped with armor-piercing (AP) rounds, this lets you deal with Zeds that have armor, like Siren or Husk.
Sidearm	Krait: The best fit for Commando’s build, it helps rotate your weapons more easily as a fully automatic weapon with high capacity.
Tool	Ammo Bag

Team vs Solo

Commando‘s build and gameplay are designed to support the whole team during matches. His DPS damage is lackluster, so much of his use comes from managing weaker ZEDs, letting other members focus on other targets, and supporting the team by providing ammo support and using gadget skills. It isn’t recommended that you use Commando for solo runs as well, just because of how insufficient his DPS damage is.

Tips For Playing Commando in Killing Floor 3

Take advantage of the many skills that support your team, such as the Get Loaded skill, which can help with reload speed.
The best tool for Commando to use is the ammo bag, which helps you and your teammates with ammo.
In early game, prioritize Fire Sale and Preferred Customer skills to get better weapons. It also lets you focus on other skills during late game, which can help you with personal damage and team support.
Gadgets such as the drone you can use are important tools to assist in overall damage during matches.
