For more detailed explanation better if you read Goldratt's Theory of constraints and for beginners introduction good books "the goal" (1/2/3). Also good to read classics - Sun Tzu, the Art of war, it is very short but unfortunately written on old Chinese, which nobody knows, so different translations are significantly different, best if read all translations you could reach in parallel and compare.

Javelins are made with strict reporting, and considered to storage few years. American/European medicine working on evidence based principles and strict protocols.

But at war and emergency, strict protocols usually disabled (and planned operations shift right), because they are extremely slow and expensive, and most Western weapons and supplies are not stored significant time, they near immediately consumed.

And also important, bureaucracy is not good, but Ukrainian bureaucracy now is just disaster, fortunately Ukrainians smart and good in peer interaction, so always when possible, better to use lower level.

So exists few variants to help:

1. If you will help to medicine, via some large fund with their bureaucracy, well, I'm not very optimistic on effectiveness, but I'm grateful.

2. If you find some way to help buy weapons, like Bayraktar heavy drones, also via some big fund, this is better. I'm also grateful.

3. The best, if you hire me, or with your support I'll make my business, probably open source. In this case will be triple win: First, I'll make decent product, I feel very strong importance of tech for community; Second, I will have some predictable future, so I could plan my life and care about health, not wait for medical emergency, so 1st variant will be just not happen with me; Third, I will spend time to talk with Ukrainian military people, I think you understand, they could tell much more to me in private talk, than for people abroad, and I will try to make them best help for this time.

As example, what I could do, FPV drones, which are less effective then Javelin, but cheaper and cost effectiveness of drones is much better. Second example, all drones very depend on communications, I'm really good in communications hard/soft, so I could make things, to make Ukrainian drones communications more reliable, and to interfere enemy communications or intercept them. And others and others. We here at HN, are knowledge workers, all we talk about gather information, store information, and process information, and you might know, knowledge at war is literally life, because with modern weapons, people in many cases don't see enemy, just got info from intelligence that enemy in location X,Y, and who will make successful fire first - will survive.

To be strict, now Russians still have significant advantage in heavy and modern weapons, and strong intelligence, and for them typical to attack civilians, so anything what make more heavy/modern weapons for Ukrainians and less heavy/modern weapons for Russians, will made huge impact on volumes of work for medics.
