If you don’t understand calculus it is going to be more difficult understanding subsequent math and science courses. You are really digging hole in many career paths.

I still have the lumps on my noggin...
Calculus is difficult because you are weak in trig, you are weak in trig because you never understood geometry ...
Or something like that.
This is true. However, how much calculus does an army officer need if his primary future career path is to kill people and break things?
Yep, functional calculus ability is mandatory in most of the sciences and all of the engineering fields (except environmental engineering IIRC).
Calculus is a big step past the mathematical rigidity of algebra, trigonometry and geometry (1+1=2) and more so dealing with moving targets (1+1= 2 at what rate or what time in the future). It twists the thought process and brain.
For myself, I never had to directly work through solving differential equations one time after college. However, the brain training was essential working through complex situations.
By brain training, I use this concept as conditioning the brain towards how to think as opposed to what to think. Calculus, I believe, opens that door. From others I have crossed paths with, I think that classical philosophy, theology and literature also train the brain in that way. YMMV on this opinion.
