Area Fire means aiming at any available targets in a particular area. In LSN this is determined by the Opportunity Fire option, leaving a straight yellow fire axis.
Assault Element is the unit responsible for the main attack. In an ambush, they wouldbe assigned different firing areas in the kill zone.
Dead Spaces are areas out of sight of the ambushers. For example, a group on a hillmay have a good view of the trail, but may not be able to see into a gully right below them. These areas should be booby trapped or targeted for accurate grenade fire.
A Fire Team is a four-man element where infantry tactics are built neither on the infantry platoon nor the squad, but on the four-man fire team. The fire team is an independent unit, and they are routinely employed separately.
(FP) Value of deployed unit, helps to keep balance of play. A Commander is worth 3 FPs, while a Grunt and Medics are only worth 1 FP each.
Force Point
Describes using indirect fire from Grenadiers in Denial of Area attacks - massive amounts of grenades down potential enemy travel paths. Works well with short-bounce technique and is a good way to defend against a Spawn Buzzer Rush.
Kill Zone is the area where you plan on shooting the enemy. It should be a placewith limited or no cover, limited escape routes, and little or no opportunity for the enemy to return fire.
Point Fire is when you're aiming at a particular target. In LSN, this is determined by the Direct Fire option, leaving a straight red line.
Security Elements have the responsibility for keeping everyone else safe. For example, if a unit had set up an ambush on a hill, the Security Element will patrol the back and sides of the hill to prevent a rear or flank attack.
Support Element is a back-up or reserve unit. In an ambush the Support Element is often set along possible escape routes so the enemy will be trapped.
Suppressive Fire means you're trying to get the enemy to keep his head down. This can be done in LSN by targeting a direction, and is shown by a purple line. Most effectively used by grenadiers or in covering a specific target area by several troops in order to defeat the 'popup' tactics of Grunts.
