Training requirements
It can be very hard to narrow down what sort of training is the correct training for any team or individual. There are always new technologies, threats, and vulnerabilities each and every day. One place that can help a newer team is to start building a baseline of what could be required from each position within your team based upon NIST Special Publication 800-181 Revision 1 (https://nvlpubs.nist.gov/nistpubs/SpecialPublications/NIST.SP.800-181r1.pdf).
This framework has all of the standard roles broken out by function that you can then look closer at. Each will have a breakout of typical skills and knowledge functions that are required to perform the tasks expected of those roles. Take time to design and document the capabilities you want in a hunt team. Once you have your baseline established, start building—or hiring—people toward those goals, then grow them beyond that.
