The B-25C has three arsenal selections:
1) Glass nose, fewer nose/blister guns resulting in lower ammo, but has a nose gunner and a bombsight
2) Strafer, more Nose/Blister guns, more ammo, but no nose gunner
3) Strafer (with glass nose), same as plain Strafer, not quite sure what difference is.
Strafer's allow the nose gunner to be manned, even though there is no gun, so make sure you have selected the right loadout in the hangar.
