In Battlefield 2, the PP-19 is issued to the MECAnti-Tank Kit. It is very similar to the MP5, with the exception of the additional 15 rounds to each magazine. This gives the PP-19 a slight advantage over the other submachine guns.
"The PP-19 Bison is a Russian developed SMG using a large capacity horizontal helical style magazine. It shares many things in common with assault rifles and is primarily based on the AKS-47 but it is considered much more accurate than its assault rifle predecessor."
"Submachinegun developed in Russia, featuring a helical high capacity magazine."
— Battlelog description
The PP-19 comes in the Back to Karkand expansion along with 9 other weapons. It has a 54 + 1 round magazine despite the game saying otherwise. The PP-19 is unlocked after completing the assignment Familiar Territory, which requires the player to:
It has a fairly long reload time for a PDW, and due to its very low damage at range, is highly ineffective at longer ranges when used without a zoom sight. However, Its high rate of fire, large magazine and low recoil makes it highly effective at shorter ranges. However even at close quarters combat, the PP-19 is still outperformed by a lot of assault rifles, carbines and PDW's in terms of the time it takes to kill, as it deals the absolute lowest amount of damage of any firearm at close range, requiring a highly unusual minimum of 6 body shots to kill a target.
As of the December Soldier Upgrade, players will be able to equip on the PP-19 the Digital Woodland Camo by default and can also equip the Desert Stripe Camo once the PP-19 Specialist assignment is completed.
