What if one could use a high-low mix here as well? There might not be enough money, people or facilities to quickly build enough of the more complex weapons. Something simplified might be good enough for less defended and less hardened targets. For example NLAW is a considerably cheaper anti tank missile than Javelin, and both are very useful weapons.
