Paras and marine commandos are also allowed to grow beards.

I assumed soldiers helping with disaster relief are less likely to be special forces.

That's probably a fair assumption, OTOH paras and commandos are "projection" force so one could expect them to be able to arrive very quickly and set up with little to no resources. Wouldn't be the worst disaster relief force early on.
