.1. "Tripwire flares"
I put quotes around it, 'cause I don't know what it is called in English. Anyhow, my bro said they used "tripwires" connected to a small device that, as soon as you step on the tripwire, goes off, but instead of exploding, it sends this beacon of light / flare up in the sky, notifying you the enemy's position. I'm not sure about the possibility of flares, but I like the idea of this.
Take Mestia for example. The enemy wants to try and sneak up from the north, but you laid some "tripwire flares" at several locations. The enemy steps on it and "voom", flares flying towards the sky. From the towers, you can easily spot it and exactly know where the enemy is.
If flares aren't possible, smoke could also do. I imagine the "officer's smoke", but thicker and shoots a lot faster up in the sky. Perhaps with a certain bang, but I don't know what it does in reality.
I think something like this will affect gameplay. It's advised that maybe a requestable kit can do this, otherwise it'll be "overused" and then everybody hates it.
Tripwire may not be possible, so I suggest using the "claymore object-properties", so you have to place a device that goes off as soon as you're near it.
2. Camoflage
Camoflage, maybe as a Squad Leader's "structure". Place camoflage in certain areas of the jungle. The idea is to hide behind it, or hide something, provide extra cover, etc.
Though the idea is nice, I haven't figured out how this would really affect gameplay yet.
What do you guys think of this?
) hs got a lot of stories from when he was in Bosnia and stuff about usin stuff like trip flares,
For the insurgents, I think they'd rather just level the whole building when someone triggers a wire. I dunno, just fits them more than some noise and light
