Military/government use of commercial-off-the-shelf (COTS) equipment
is certainly nothing in any way unique. I did nonetheless find it
interesting to stumble across a few well-known (to radio enthusiasts)
receivers being integrated into IEI's product offerings:

Integrated within the HF/ VHF/ UHF TACTICAL RADIO MONITORING SYSTEM
[ TRM-1-2000 ] are two Icom IC-R8500 receivers.

The HF/ VHF/ UHF PORTABLE RADIO [ MONITORING SYSTEM (PRM-1-2000) ]
integrates three AOR-8200 Mk III receivers into a brief case w/a
laptop (and optional direction finding gear)
