Hello fellow Arma 2 players,
In this guide i want to show you how to accurately employ the Carl Gustav's 'High Explosive Anti-Tank', or 'HEAT'-shells, at ranges far beyond what the scope originally implies.

While using the Gustav myself, i saw how the Gustav's sights were downright inaccurate at certain ranges, making your shell overshoot most of the time.
After an afternoon of checking, testing and re-checking, i came up with a list of numbers which proved far more reliable, and accurate at ranges up to (ànd over!) 1000m.

I hope these numbers will prove valuable to you as well, and help you achieve the most from this impressive AT-weapon.

This is your default Gustav sight.
It has an integrated rangefinder, and distance-crosses to properly elevate the launcher to engage distant targets. The point where the distance is measured (displayed in green numbers) is right underneath the top chevron: ^

For example: this grey shed in front of the oilderrick is 525m away:


Following the appropriate numbers, these are your sight-pictures for the corresponding ranges.

Sight for a target at 100m:

Sight for a target at 200m:

Sight for a target at 300m:

Sight for a target at 400m:


Note how at the further ranges the sight is elevated to such an extent, that the ^-mark now measures a point much further than your initial target. Don't let that confuse you: First measure the distance, remember that distance, thèn line up your shot - while ignoring the now changing green number.

At 500m though, the original sight is horribly off, making the shell land way beyond the target:

This is where you have to adjust your sights to very specific points in order to score a hit.
I always keep a list of these numbers nearby for quick reference, and i suggest you do the same.

For a 500m target, simply use the '4'-mark:


For a target at 600m or 700m, you have to aim for what i call the 4.25 mark.
Bracket the target inbetween the '+' cross for number 4, and the '-' line for 4.5:


At 800m and 900m put the 4.5 line '-' over the target:


For 1000m and 1100m (we're already at a kilometer now) aim for 4.75.
Bracket the target inbetween the '-' line for 4.5, and the '+' cross for number 5:


Still not done. :)
To engage a target at 1200m or 1300m, place the '+' cross number 5 directly on the target:


As final icing on the cake, you can even engage targets at 1400m and slightly beyond.
I find placing the '+' cross number 5 at the top edge of the target works best.

Here is a small demonstration of how an engagement at such long ranges would work.
These two screenshots show both viewpoints - from the AT-gunner to the tank, and vice versa:

With the scope's rangefinder, i see that my target (a T-55 tank) is just over 1.5km away.
Using my range-card - as explained above - i place the nr.5-cross at the top edge of the turret.











Carefully move your cursor on the apropriate point, since targets are incredibly small at these ranges.

Even a small nudge of your mouse can make you miss your shot...



It takes about four and a half seconds for the HEAT shell to travel the 1500m.
Note the red arrow that indicates where i fired from.

These are the ranges i mentioned in this guide, and their corresponding sight-points.
Again, i suggest you write it down / print it out, and keep it handy for quick refference.

Range:______Aimpoint:
__100m ---------- 1
__200m ---------- 2
__300m ---------- 3
__400m ---------- 4
__500m ---------- 4

__700m ---------- 4.25
__800m ---------- 4.5
__900m ---------- 4.5
_1000m ---------- 4.75
_1100m ---------- 4.75
_1200m ---------- 5
_1300m ---------- 5
_1400m ---------- 5 (at top of target)
_1500m ---------- 5 (at top of target)

That concludes my guide on the Gustav's HEAT employment.
HEDP-shells are a different story: those things plummet to the ground very quickly...

I hope this helps you out ingame, and feel free to send me any suggestions, corrections, etc.
