There are a couple of definitions for ICOM, but in this case I think you mean the acronym for Integrated COMmunications.
I intentionally left the Security (un said SEC) off of my repsonse because I have seen it used both ways, with and without implied SEC. Yeah, I understand (or think I do, anyway) the inclusion of Security is how the Acronym was origianlly derived.
It varies a bit from community to community, but I have seen ICOM (implied but not said SEC) used when discussing either own gear or OPFOR and integrated security (encryption). And I have seen ICOM (without the SEC, so just Intergrated Communicaitons) when discussing OPFOR that has no encryption. Example, monitoring in the clear transmissions using something like an AOR.
T!
Interesting, I guess I always "read" it as having the "SEC" included but in many cases that was an assumption based on the context...although as stated, a lot of comms are in the clear using good old VHF/UHF gear that's available as COTS equipment.
From Luhansk to Idlib, HAM radio gear in conflict short of war is alive and well. There's a vid somewhere on innernets of the kurds listening via HAM radios to isis commanders bitch about not getting their fair share of lamb when the other isis asshat got his, Afghan soldiers taunting isis asshats over the air, Ukrainians and NovoRossians taunting each other via v/uhf, etc etc.
Thank god for China and the barfing dual band hand helds!

Dunno if this applies to the barfing rigs, but the one I had, canna remember the brand, had a over the air lock out feature, if the radio received the code it was locked out and shut down or something like that. Inscrutable, those Chinese.
Plenty of pictures of Ukrainian military, militia and Russian "little green men" with UV-5Rs, UV-82s and other similar Chinese VHF/UHF HTs as their inter-squad and intra-squad radios. One of the articles I've read about Russian signals intelligence activities in Ukraine involved transcripts of chatter between Ukrainian militias on 145.xxxx MHz frequencies. I know that, like the Japanese radios they're cloning to various degrees, some of the Chinese VHF/UHF gear has "remote stun" and "remote disable/enable" capability included as part of the various selective calling (DTMF, CTCSS, DCS) capability of those radios. I can't say for sure about the UV-5R in particular, however.
Integrated communications security using $30 Chinese VHF/UHF handhelds? The best you'll get is maybe voice inversion. Makes me wonder if there are militia commanders in Ukraine ordering a pallet of Baofengs and programming all of them up with the same channel plan or just leaving each unit to their own devices.
The AOR receivers
are military-grade radios apparently, especially compared to the bowww-fengz - which are surprisingly tough little radios. I have used the UV-5R extensively for backpacking, hiking, driving two cars across Europe (no seriously, using the PMR446 UHF license free frequencies) and FRS/MURS and even Part 90 land mobile work and they're good little radios. They don't have the intermod rejection capability of a Motorola but for the price you can't go wrong....and if you're fighting the Russians on a budget I have a feeling they fit the bill quite well.
