The AN/PAS-13 and its sub-variants are infrared scopes used by several BLUFOR and INDFOR factions in ArmA 2. They were added with the release of the Operation Arrowhead expansion pack.

This is a premium asset that requires ownership of the Operation Arrowhead expansion pack.

The AN/PAS-13 is available in three separate variants designed for use with different firearm calibres, ranging from 5.56 mm up to 12.7 mm (.50 cal).

All variants can only toggle between a black-hot/white-hot thermal vision modes. They cannot be switched to an unfiltered day vision mode.

Depending on the variant some may also feature integrated laser rangefinders, though not all models have this capability:


LTWS reticle

"Lightweight" version. The LTWS is tailored specifically for use on 5.56 mm NATO and 7.62 mm NATO-chambered firearms:

  • Mk16 EGLM assault rifle (5.56 mm)
  • Mk17 battle rifle (7.62 mm)
  • XM8 assault rifle (5.56 mm)
  • XM8 CQC assault rifle (5.56 mm)

Zeroing limits/capability varies depending on the weapon platform. The Mk16's LTWS cannot be zeroed but the Mk17's LTWS supports zeroing starting at 50 m, 100 m, 200 m and finally 300 m.

For the regular XM8 rifle, zeroing starts at 100 m and goes up to a maximum of 300 m only. It cannot be adjusted beyond this distance. The XM8 CQC on the other hand can be zeroed beginning at 100 m, which subsequently rises in 100 m increments up to a maximum of 800 m.

The LTWS reticle is a simple crosshair with a dot in the centre. The centre dot is ranged for targets at distances of up to 100 metres away (assuming no changes to the scope's zeroing).


MTWS reticle

"Medium" version. The MTWS is designed for use on 5.56 mm NATO-chambered light machine guns/light support weapons:

The MTWS can switch between two fields of view, one with a magnification zoom of only 1.55x and another with a power of 5.02x.

For zeroing, it alternates between either 120 m or 400 m; the user cannot increase the zeroing beyond these two ranges.

Ballistic drop compensation markers are provided on its reticle that are ranged for targets beginning at 120 metres (the centre dot), 200 metres for the dot immediately below it, 300 metres, 400 metres and lastly 600 metres at the lowermost mark (the fifth and final dot).


HTWS reticle

"Heavy" version. The HTWS is intended for exclusive use on heavy weapons like 12.7 mm anti-materiel sniper rifles:

  • AS50 anti-materiel sniper rifle (12.7 mm)
  • M107 anti-materiel sniper rifle (.50 cal)
  • M110 sniper rifle (7.62 mm)

Like the MTWS, the HTWS features two fields of view with a magnification of either 3.31x or 10x power. Zeroing limits are dependent on the weapon platform; for the American M107 it begins at 100 m and subsequently rises (in 100 m increments) up to a maximum range of 1200 m.

The M110 has the same minimum range and increment amounts as the M107, though it only goes up to a maximum of 800 m instead.

For the British/PMC AS50, the ranges are also the same up until 800 m. From that point onwards, it rises in 200 m increments (not 100) until hitting a maximum of 1600 m.

Its reticle is based on a conventional mil-dot setup. The centre dot itself is ranged for targets at 120 metres assuming a default zero of 100 m. The eight horizontal bars below it represent ranges for 200, 300, 400, 500, 600, 700, 800 and 900 metres, though it can vary depending on whether the user has adjusted the zeroing or not.


  • Unlike real AN/PAS-13s, the in-game versions are not capable of switching their reticles. All models of the scope in real-life have programmable reticles which can be toggled by the user to better suit their weapon platform.
