Blocked fire is only mentioned in 7.24 and 10.1:
7.24 Blocked FireUnits may not target direct fire at a hex containing friendly units, nor may they trace direct fire through a hex containing friendly non-armored units (exception: see
10.1). They MAY target bombardment fire at an assault hex. They may also target anti-tank fire at an assault hex IF there are no friendly vehicle units in that hex.
10.1 Blocked Fire
Direct Fire may be traced through vacant hexes, enemy-occupied hexes, or hexes containing only friendly AFVs (enemy-occupied or not). Direct fire may not be traced through hexes containing friendly non-AFV units unless the firing unit is an HMG, AFV or antiaircraft unit. These units may fire "through" hexes containing all types of friendly units, IF the fire is also traced through at least one hex which:
- Contains no friendly units, and
- Is between the target hex and all friendly units along the line of fire.
This rule applies to units firing from a higher elevation through their own troops on a lower elevation as well.
Neither pertain to AT fire, so AT fire can go through friendly units. So, the answer to the OP's question is "yes."
