What do Rapid Recruitment and Bannerman's Bargain do?

Two Infrastructure nodes that speed up and cheapen troops — crucial, because combat demands several waves (so a lot of troops to replace):

• Rapid Recruitment: −37.5% training time (at level 11). You replace losses faster between waves.
• Bannerman's Bargain: −30% troop training cost. You produce more troops from the same resources.

➡️ If you actively farm the map and seats, these two nodes pay for themselves: less waiting and fewer resources to rebuild your armies after each round of attrition (−300 to −600 troops per round).
