Ideas how to improve WinSP MBT/WW2 !

[Imp]

Just out if interest bought 6 Apache,30mm, Hellfire, 2X DAGR config
Map fairly open trees woods hills.
Moved to take up positions on first turn,
Set ranges to 20hexes.
After that did nothing did not move or fire in my turn, just hit end turn.

Opposing side no AAA assets
Platoon tanks
Company APCs
2 Companies of trucks as soft targets
2 Companies dismounted soldiers.

Results once in range, one vehicle might have survived for 2 hexes all rest killed once in range.
Autocannon got a high percentage with around 66% hit chance, hellfire finished with 90%hit if missed.
Infantry hit chance around 34-40%.
After a few turns probably lost about 25% of their infantry & getting any to advance was getting difficult.
As said this was all reaction fire I never targeted a unit or moved after turn 1 I just let the enemy advance.
