Help! I lose too many units on CS/Gangs

If you look back and check the helpful links I've posted, you should see the chart.

Lv2 & Lv4 Gangs will take zero losses on with Hitmen On Lv2 and Enforcers on Lv4. Use 4 Hitmen on Lv2 and use 30 Enforcers & 1 Truck on Lv4 (Truck to bring back resources).

I know the chart says use 20 Enforcers on Lv4 but i found that 30 work with zero losses regardless of armor and/or research levels.

What about other Gangs & Cityscapes?
Use Arsos. By this time your workshop should be nicely leveled, close to Lv9 if you been working on it. If the chart says 200, use 300. If it says 1.1k use 1.2k.
