Please add M49A1 surface trip flares.
This was a miss with the Arma series and it had to be scripted. Surface lighting would add an immensely interesting visual aspect to night time gameplay. Triggering the device would alert and silhouette those in the vicinity at night. It serves as an early warning device and doesn't harm the player that triggers it, which makes the gameplay better than going unconscious/dead that anti-personnel mines would introduce.
The US M118 and M119 tripwire flares were also used extensively in training, as well.
It's understood that this will effect performance, but used in small numbers this would enhance gameplay in a manner that a mines would not.
