Mission 1 was really important... The opponent was focusing on my AT gun and I have played along by bolstering it once. Damage was inflicted twice to it, and the rest of the damage was inflicted to both of the buildings where I places my machine guns and snipers. What I did was I leveraged the fact that I've only killed reservist rifles to snipe high impact units of my opponent and then, after drawing poorly, went all in on winning the initiative to forfeit.
Mission 2 was meant to be a carnage, but I have utilized my close range machine gunners and the guide from platoon B to deploy snipers at the end of round 2 and win with the full route on turn 1 of round 3. I lost a regular army machine gunner as the result, but gained control of the Northern Reach. With the nazis fleeing, it's up to me to convert more mobile elite force with a better morale into a decisive victory, running away with the campaign.
