Please Check with our Sponsors before you order from a Non-Sponsor Website.
In many, and most, cases our sponsors have superior products for a comparable price point.
However, certain components, namely those for comms, can be a rather niche product field.

https://www.evike.com/products/67209/   Airsoft Grade (Meaning “Field Legal”) smoke pull ring. These can put out a large volume of smoke for signaling or masking.
J.P.’s notes: Smoke is used for Signaling by day, Smoker Generators (Typically Vehicle Mounted Units or are munitions for Indirect Fire Weapons) work much, much better for concealment and are leaps and bounds ahead of ANY handheld unit.
Perimeter Protection- Concertina Wire is a ridiculously effective piece of kit. You will need the C-Wire Gloves for handling.
