-Reinforce cost increased from 22MP to 27MP.
-Squad cost increased to 300 manpower and 27 reinforce from 270 manpower and 22 reinforce.
All squads in game have the reinforce cost = 50% of model at max. Some are lower (PG, Tommy) due to mp drain complaint.
For penal, it would be 270/6 * 50% = 22.5, or 22 mp.
If squad base mp is 300, then the reinforce at max should be 300/6 * 50% = 25.
Be careful with balance. Know the basic first, otherwise, you just make another error like Relic did.
