what is the line?
<UnitCombatType>UNITCOMBAT_ARMOUR</UnitCombatType>
<bFreePromotionUnitCombat>1</bFreePromotionUnitCombat>
</FreePromotionUnitCombat>is that the line

It's spelled UNITCOMBAT_ARMOR (without U).

You also need to specify what promotion is given under <FreePromotions>, unless you're just adding armor to a trait which already gives out free promotions.

thanks the this will be added to the agressive trait(instead odf guns)if it works

free promotions for tanks could be also used to form a new 'technical' trait
