Arab vs Israel Campaign

[Imp]

ATGMs generally best engagement range is between 30 - 90% of their range, my prefrence is to engage at range in the hopes of staying hidden. That said firing at max range is fine for a lot of ATGM,s, top attack are the exception if you need it to penetrate the target as top attack is less likely to occur at extreme ranges.
If an ATGM is part of a platoon don’t normaly set it up with them, set up well back if terrain allows LOS they can screen with RPGs if enemy gets to close.

Versus the dug in tanks with yours it’s hard but you should be firing at them with consecutive fires so your accuracy increases.
Alternate fire with your furthest units to draw fire, they can target anything useful the chances of them hitting are minimal then switch to your closer units.
