SpecOps is a series of 10 short stories in the Reborn Federation time period. Rangers, Delta, SEALs, even the Cadre are visited.
Ahem:
"For thousands of years military forces of many
species had an elite unit of some sort. Terrans had many branches of elite
units that served a special purpose or mission type that regular units would
have been hard pressed to perform.
When the Federation was formed the Terrans became
the model for many things, including the Special Forces units. Some became
legends in short order. Others were quite secretive, preferring to do their
work in the shadows without being noticed or acknowledged. During the Xeno war
they fought the Xenos hard and worked to pass whatever intelligence they could
back to command.
In the Reborn Federation, Admiral Irons passed an
order to begin training these elite units once more. The Marines started the
process with the Force Recon Marines. The process was carried up to the
greatest of all, the Federation Cadre.
Here are some of their stories."
