Security

Sandbags - Provide good cover, excellent for defensive firing positions.
Mortars - Long-range and very damaging but require ammunition, have long warmup and cooldown times, and are highly inaccurate.
Traps - Passive structures that inflict a one-time injury until they are reset. Enemies can avoid a trap once their faction has learned of its position. As of version 0.15.1279 (29 August 2016) chance to spring known traps is reduced from 2.5% to 0.4%.
