[DS] Need help with Phalanx

Hello All,

	I was attempting to make cards for future mini expansions 
of my force. When I went to do the FV202 Phalanx I ran into a 
problem. Either I am doing something wrong or the vehicle as 
written in Stargrunt can not be done in Dirtside. 
Help me please.

Phalanx Size 4 vehicle
	4x5=	20 capacity points

DFFG/1 in Turret = 1x3 =  3pts
DFFG/1 in Turret = 1x3 =  3pts
4 Troop Elements = 4x4 = 16pts
	  Total Points = 22pts

Even though the two DFFGs are in separate Turrets let's take one 
down to only 2 points? Still 21 points. 

Am I missing something here?
