Two remarks (after viewing the Austrian set-up at start):

You've given fortresses C0 through E2 40 rounds sabot ammo for the 105 m68 gun. Unfortunately that gun has an APCR value of 0 so these rounds are useless.

You've widely dispersed the squads from the platoons effectively cutting many of them off from their command unit (and often with little chance of getting back in contact). That will severely limit their effectiveness. What makes it worse is that in some instances you deploy squads/teams from different platoons in relative close proximity. It would be far better to use units from the same platoon in the same sector.
In fact try to deploy the bulk of a platoons units within 5 hexes of the command unit.
