How do you unlock the UMP45?

The UMP45 is available once Create-a-Class opens at Level 4 in Call of Duty: Modern Warfare 3 (2011). It is a default 32-round automatic SMG. Its measured cadence rewards accurate opening shots and short bursts rather than trying to imitate the faster close-range guns. Its camo track finishes at Gold (Reach Weapon Level 31 with this smg).

Proficiency notesRange at Weapon Level 9 builds on the deliberate role; Focus at 15 helps preserve aim under fire
Challenge noteReach Weapon Level 31 with the UMP45 to unlock Gold. MW3 (2011) does not use a headshot requirement for this camo.
Progression tipFavor controlled close-to-medium engagements and attachment challenges instead of holding the trigger through every route.
Camo tipPlace the opening rounds and use cover if they miss rather than lengthening the burst.

Weapon levels are tracked per weapon, so each camo must be unlocked separately on each gun. On the UMP45 the final tier is Gold — Reach Weapon Level 31 with this smg.
