I made an image to show where all the health and ammo spawns are located in the map. Blue is health and orange is ammo. There are 2 medium health in total both are the ones placed closest the bottom (one at A, and one at B). All other health pickups are small. the ammo is mostly small-medium, the single full ammo is in the B-C connector.
Compared to gravelpit, this map has slightly more health. I probably wont be adding more, but if anyone has any placement suggestions I'm all ears

Personally, I think its good as it is. But you never know, someone might have some really neat ideas to share.
Summary:
A area: 1 small, 1 medium health
B area: 1 small, 1 medium health
A-C connector: 2 small health
B-C connector: 2 small health
C area: 1 small health
