This is a map that I don't believe rewards defense as much as it does attack.  For that reason only delta squad will have a Plan-B defensive strategy. 

Alpha Team
[1] Assault (enfield) – take the quickest route to the middle flag and at the beginning of the round try to be the first to cap it.  Hold and control the third flag road until our sniper can get into his stage two position where he can take out any allied snipers.  When he's in a covering fire position, advance and provide [2] with some rifle cover.  Make use of the bombed-out building for cover. 
Responsibilities: cap the 3rd flag; advance and provide rifle cover for [2].

[2] Assault (sten) – take the main route to the middle flag and enter the lefthand building, clearing out any axis inside.  When a majority of the axis have died, jump out the window and make for the bombed-out building situated just before the fifth flag.  Ambush the next enemy wave that comes through and attempt to cap 5th flag. Go on to spawn camp until all the flags are captured.
Responsibilities: control the thrid flag left-hand building; cap the fifth flag; spawn camp.

Bravo Team
[3] Assault (sten/enfield) – take the main route to the middle flag and go up the right hand flank leading to fourth flag. Advance under cover from [4] and cap fourth flag. Advance onto fifth flag and attempt to capture.  Go on to spawn camp until all the flags are captured.
Responsibilities: cap fourth flag; cap fifth flag; spawn camp.

[4] Assault (enfield) – take the left flank through our second flag and hold the two storey building.   Cover the passage leading to fourth flag and, if the majority of our team is alive and advancing, follow [3] through the right hand flank and provide him with rifle cover.  Cap fourth flag if not already done and move up to snipe through the doorway leading to fifth flag.  If attacked, retreat to a better position and maintain our control of the fourth flag.
Responsibilities: control our second flag and our two-storey building; hold fourth flag area.

Delta Team
[5] Support (enfield/sc-enfield) – go through the connected buildings just outside our spawn and get into the sniper window overlooking middle flag. Cover the middle flag until the first axis wave is dealt with and then move into your stage two position.  When our team is making their final push on the fifth flag, advance to stage 3.
Responsibilities: take out any enemy snipers and cover our team's advance.
Plan-B: Should we go to Plan-B, cover our first flag from one of the windowed buildings until we control our flags and the middle flag.

[6] Support (bren) – take the left flank through to our second flag and set up (possibly near or behind the tree) looking into the two-storey building.  When we have four of the five flags, advance up the main road using the sandbunkers as mg stations.  However should they repel our final assault and stage a comeback, resume your stage one position
Responsibilities: hold second flag.
Plan-B: Should we go to Plan-B, take up a defensive position on our first flag until we control our flags and the middle flag.
