You can tell great thought was used to make the cards. The deck is thoughtfully illustrated to understand clearly all direct motions. One side gives description, other side has name and illustration with easy to understand directions. Very impressed.

Another item that I keep with tactical, training, survival and emergency gear. I have many other card sets in this category and they all work together well.

Another reviewer suggested a future printing with playing card suits and ranks on the backs. That would be so cool! I have a set of plastic weatherproof playing cards that feel very much like normal coated paper playing cards. I think a great upgrade would be for the signal cards to be remade as a plastic deck with signals on one side and ranks and suites on the other.

The price was right and I was curious so I purchased these cards. After looking at them I realized that although my special ops opportunities are way behind me, the cards had a practical value as well. Hunting, wildlife observation while hiking and even communicating with my wife on her lawn tractor when she is wearing hearing protection. "Yes, no, understood, come this way, go that way, come here." Everyone should get them.

Nicely done.
I think that a future improvement would, could, should, include (four more cards) regular ranks and suits printed on one side. Then they could also be used for regular card games.
I have a deck of edible plant cards, done in a similar manner as I described.
One side of each card has a picture of a plant, the other side has a rank and suit ddesignator along with a description and information about the plant on the other side.
