Template:Hint type table row 101
From Valve Developer Community
|- valign="top" | Crouch Cover Low | 101| Tells an NPC it can find cover at this position if it crouches low (calculated at 40 units height). Can cause animation issues with npcs other than combine soldiers; they will tend to duck down and than immediately stand up. ai_goal_standoff can fix this.
Placement Tip: This type of cover can be broken easily, which can cause ai issues. Use with caution.
