Well you already know about this paper as I posted it on your last thread: https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/products/vsphere/vmware-vsphere-vsom-pricing-whitepape…
You'll need vSphere licenses for your 30 hosts (at least Standard level to get vMotion), plus vCenter Server Standard.
vSphere licenses are per CPU, so if you have dual-socket hosts you would need 60. vCenter licenses are per instance, so just 1 of those required.
All of that is explained in the licensing paper.
No idea on the armed forces part.
You'll also be required to buy at least 12-months support - you should go for at least Production level: On-Premise and Hosted Support Offerings: VMware
