   What would you like to know?  Harris makes a decent portable radio with encryption capabilities, and Motorola has their APX line, with encryption available as an add-on.  What frequencies were you planning on using the radios?  Some encryption is better than others.

Here is something to read about this subject to educate the group before we get started on this subject. http://www.tacticalrepeater.com/radio-encryption/

The best encryption when TXing on a radio is using a Brevity Code.

NC Scout facilitates a great class on this subject called RTO. Patriotman and many others here at UP, have taken this class along with the Adv. RTO class.

A agreed upon code words and phrases are developed before each mission. Each mission has different code words and phrases.

Here is an example of a SALUTE report/exchange with a TOC (Size, Activity, Location, Uniform, Time, Equipment)

Quote
"Tango Tango.. Bingo Bingo"

"This is Tango... go ahead Bingo"

"Line one"..."Hog, Eagle -Break"                              (2, enemy)
"Line two"..."Dancing with wolves - Break"               (Enemy patrol)
"Line three..."GD/BD - Break"                                 (Grid BB/30)
"Line four...Chair, table - Break"                              (Russian Camo)
"Line five...TG/XX - Break"                                      (1200 hrs)
"Line Six...Cake, spoon, cup - Break"                       (AK, RPG, Night vision)

"How copy Tango?"

"Good. Tango clear"


That is a 30-second burst of information from the patrol to the TOC. Some times the TOC will say, "repeat line X." as the transmission was garbled. The patrol would reread that line and say again, "how copy?"

Typically a directional UHF or VHF antenna would be used which was aimed towards the TOC. Once the transmission was done, the patrol would move at least one kilometer away from the TXing location.

This description is simplistic and to really get the drift you need to go to NC Scouts class to learn it. Then practice, practice, practice.

Something thats affordable enough to buy 3,4 or even 5 for the group.
That encryptis from each unit.
Easy to use.

Encryption does not need to be extremely high end.. if its gets broken by OPFOR eventually I dont care I just want to deny real time intel to any hypothetical enemy

I second the BREVMAT. Also, commo windows.
Blessed be the LORD my strength, which teacheth my hands to war, and my fingers to fight: My goodness, and my fortress; my high tower, and my deliverer; my shield, and he in whom I trust; who subdueth my people under me.

Loved the BREVMAT idea, here is a nice article about it http://quietsurvivalist.com/the-brevity-matrix/

Also I wouldn't trust on commercial encryption hardware, specially if you plan on hiding from gov, and for encryption to work you need to talk with other devices that are compatible with the encryption.

A key factor in comm security is that they don't know you're there, long comms can be triangulated and your presence in the area revealed, if the OPFOR catches you they will be able to know you're the one who were transmitting in code.

My suggestion would be, regular radios using short comms, for instance with BREVMAT and using directional antennas with the minimal required transmission power.
