Target Acquisition Gear (TAG)
Simply known as TAG (Target Acquisition Gear) systems are used by infantry, recon and various other units to allow for indirect fire to be brought to bear. There are two types of these systems. Basic TAG (B-TAG) and Advanced TAG (A-TAG).
Unlike basic systems which use a solid beam that is easy to track back to its source, A-TAG systems “ping” targets with a concentrated RF burst which the TAG uses to calculate and transmit its geometric coordinates. The coordinates can then be read by any indirect fire control, such as LRM, mortar, and artillery targeting computers, allowing them to lock on to the target without being able to see it. These systems are very light but also very expensive. They are usually reserved for infantry and recon units that require absolute stealth.
Basic TAG systems use a steady beam of RF or Light, to direct fire to the target. The pros to this system is that it is less complicated, more durable and much cheaper than the advanced system. The drawback is that it is very easy for the enemy to see where the beam is coming from. This is why B-Tag systems are usually fixed to units that aren’t going to be hiding during a battle, such as mechs and tanks. Some infantry units are still equipped with these basic systems. This is usually in cases where the budget simply doesn’t allow for the more expensive units. Needless to say, soldiers who do use them often have a short life expectancy in battle.
Ranges for TAG systems are 10-20-30. There is no minimum range. Line of sight must be maintained. A TAG system will not work through water or smoke. Rules for shooting through other terrain are otherwise the same.
If a TAG hit is successful, using indirect fire can be done at a +2 modifier.
If a target does not move after being hit with a TAG, it remains “tagged” as long as the unit doing the tagging also doesn’t move.
Any unit firing a TAG uses normal to-hit rules. Firing a TAG at a secondary target adds normally to the to-hit modifier.
Mounted TAG systems may not be fired by a powered down mech or tank. They require power to aim and operate.
Any mechanized combat unit hit by an A-TAG may attempt to detect the location of the source. Doing so simply requires the use of the unit’s ECM (Electronic Counter Measures) system. The base roll is a 10, which can reduced by various skills and technologies. Once detected, the unit firing the A-TAG becomes visible to all enemy units on the battlefield.
Note: Certain non-combat units would not equipped with ECM, and therefore would not be able to detect the location of TAG attacks. Examples would be inexpensive units like Field Guns, or rear echelon units like supply and support vehicles.
