Attacker is 3 combat strength for the 1/173, +5 artillery for the HQ (0 combat strength), and +4 (now) for the air. The artillery/air are halved b/c no free fire. so an attacking strength of 7. Defender is just a 1 strength unit with no artillery. 7:1 ratio is +5 DRM and -1 for attacking in the town hex.

Losses are on the 4-7.5 column for the defender (1 combat strength + 4 for my art./air) and on the 1 to 3.5 column for the attacker.

A range of modified 5 to modified 10 is possible. A roll of 6 would inflict 1 loss on me, all others are 0. Rolls of 1,3, and 5 inflict 1 loss on you. Rolls of 2 and 6 inflict 2 losses on you. A roll of 4 inflicts no loss. I lose an air point on a roll of 4.
