Snipe While Holding Your ground Up Close

ISO SMG has good handling and a high fire rate that is effective up close but will suffer at longer distances, so we combined it with snipers rifles to min-max each weapon's pros and cons. It can be a good pair weapons for snipers also looking to get up close and personal.

Swat Out Weapons As You Need

If for some reason the match needs you to ditch one of your weapons for something with better attachments or a Grenade Launcher, you have the liberty to do so as you can swap between weapons fast thanks to the Amed perk. This gives you more utility in the field.

Stealthed Balanced Weapon With Fast Handling

This loadout balances stealth, range, ammo capacity & handling into 1 easy-to use package. Players can use it to clear rooms & halls in Warzone to great effects but will require another weapon when dealing with ranged targets.

Reload Fast With Sleight of Hand

ISO SMG chew through ammo very quickly but its reload time is greatly reduced by the Sleight of Hand perk. If you don't feel thats what you need, swap it out for a FTAC Elite ISO Grip.

High Mobility Assault SMG

The ISO can equip attachments that can maximize its already impressive Mobility stat. You can combine all of them to make you a speed demon in the battlefield.

High Capacity Magazine Is Recommended

The ISO SMG's default 20-round magazine is enough to kill 2 enemies if you aim it right. However, getting caught in a crossfire while reloading ensures your defeat, so increase your chances of winning by bringing a larger magazine.

Use Double Time For More Speed

Double Time increases your sprint duration, giving you more time to cover ground. Use this to press forward and flank enemies. Having Dead Silence is also recommended.

Attachment Setup For ISO SMG

Tac LaserTac LaserHigh power 5mW Tactical Green laser greatly improves accuracy while aiming down sights. Exposes position when active.
ISO CollapsibleISO CollapsibleThe ultimate run and gun modification when agility is more important than precision. Collapsing the stock greatly increases movement.
50 Round Drums (ISO)50 Round Drums (ISO)Drum magazine holds 50 rounds of 9mm Parabellum, maximizing ammo capacity at the expense of mobility.
FTAC Elite ISO GripFTAC Elite ISO GripFully stippled straightline grip maintains control when performing high-speed maneuvers. Less table but very agile.

Full Mobility Attachments

All but one of the attachments mentioned above give the ISO SMG improved Mobility. This makes you faster on the battlefield, allowing you to quickly close in and spray.

High-Capacity Mag Greatly Helps

The default 20-round magazine restricts the user from getting into drawn out firefights. Although it somewhat diminishes the Mobility of the ISO, a 50-round Drum Mag improves staying firepower and damage output.
