Our highest priority without a doubt is getting that Nazi Ore. Why? To prevent Moskurg from getting it.
They do not lose control of this portion of the mountain, but the Moskurg ore supply is disrupted (Arstotzka 3/4). Failure to regain this ore will certainly end the war.
We shouldn't have too much difficulty holding the line in the Mountains, so as long as they don't get Ore from the Nazis we'll win the war.
The worst case scenario if we do nothing is that they get the Nazi Ore
and they'll get back the Mountains. If they reduce the complexity of their armour, it will become cheap, as will a bunch of other stuff. That would damage us greatly.
Our semi-automatic battle rifle is ok, but hardly anything revolutionary. Moskurg's assault rifle, on the other hand, is. What we need to do is at least match it. Considering how well we did on revising our SMG, we'd probably get good things from our assault rifle, even if we had to revise it.
Design the AS-AR34.The AS-AR34 is a select-fire, detachable magazine-fed assault rifle chambered for the 7.62x39mm round. It's capable of firing in both automatic and semi-automatic. It features a pistol grip and a foregrip with adjustable iron sights.
Since we're using the larger 7.62mm round, it'll be better at longer ranges compared to the enemy's (appeasing Hitler's desire for a rifle even more and playing to our Patient advantage) and will perform better at AP.
If it weren't for the Nazi opportunity, I would instead suggest getting our own body armour.
The few Tiger Infantry Armor suits available are assigned to bunker machine gunners and storm troopers. They are greatly effective, and the soldiers equipped with them often appear to be bulletproof heroes.
Aside from automatically getting it cheaper and thus letting us field it in decent numbers (as well as nullifying the enemy armour's morale effects), we have aluminium so it can be even more effective.
Glory to Arstotzka.
