Overrun Flowchart

Vehicle prepares to enter Defender's Location

If the Location contains any Known enemy units, any OVR must be declared before entering
In order to OVR, vehicle must not have Bounding First Fired (other than prior OVR)

Vehicle enters Defender's Location

Only fully-tracked CT BU AFV may enter a Building (B23.41)
Only BU AFV may enter a non-Collapsed Hut (G5.4)
OVR NA from Bypass (A12.42) [EXC: vs Bypass units], via Reverse Movement (D7.13), or in Lumberyard hex (B23.211)

Expend MP for entry:

OVR:	¼ printed MP (FRU [D7.1]) + COT
Non-OVR:	COT

Concealed Personnel in the Location must^* either:

Drop Concealment, or
Take one combined PAATC using the lowest Morale in the stack (A12.41). Leadership applies.
- PAATC NA for SMC, Berserk, Fanatic, HA
- 1PAATC if Inexperienced, non-Elite GMD Chinese, non-Elite Italians, Allied/Axis Minors
- Dummy stacks use ML 7 for PAATC as printed on ? counter
  - Pass: retain Concealment
  - Fail: lose Concealment and Pinned (A11.6)

* Concealment is retained without a PAATC if the entering vehicle is "broken" (A12.1) or uses Bypass or a Woods-Road (A12.41).

Terrain Effects

Check for:

Bog (D8.2)
Rubble cdr ≤ 0 on Bog Check DR (-1 drm each for Wooden Building, Single Story House) (B23.41)
Fall into Cellar - original 6 on Bog Check cdr
Hut Collapse - automatic if AFV enters (G5.4) - All units take PTC (G5.5)
Place partial Trail Break (B13.421) in Woods, Jungle, or Bamboo if Fully-Tracked AFV is still Mobile

Defensive First Fire is allowed vs this MP expenditure, DFF from outside the vehicle's hex is performed normally. In-hex DFF options vary depending on whether an OVR was declared upon entry.

Defensive Fire Options Before OVR:

	CC RF	IFT^a	LATW^c,d	Gun^d,i,o
Unmarked	No	✓	✓	✓
First Fired	No	✓	✓ ^k	✓ ^j
Final/Intensive Fired ^l	No	✓	No	✓ ^j
Pinned	No	✓	✓ ^f	✓ ^f

Vehicle Elim or Immob (including Shock, Stun, and crew K/KIA/Break) does not prevent an already-announced OVR but does halve its FP. Pin results and effects vs Passengers/Riders (only) do not affect OVR.

Defensive Fire Options with no OVR:

	CC RF^b	IFT^a,q	LATW^c,d,q	Gun^d,i,q
Unmarked	✓ ^h	✓	✓	✓
First Fired	✓ ^g	✓	✓ ^k	✓
Final/Intensive Fired ^l	✓ ^g	✓	No	No
Pinned	No	✓	✓ ^f	✓ ^f

If there were no Known enemy units in the Location when the Vehicle entered, it may now declare an OVR if still Mobile with sufficient MR Defensive First Fire is allowed vs this second MP expenditure. DFF from outside the vehicle's hex is performed normally.

Resolve OVR

vs unarmored units (including Vulnerable PRC) in the location

OVR FP = Base	4 (AFV with usable MA not MG/FT/IFE/ATR/MTR) or
	2 (other AFV, unarmored bulldozer) or
	1 (unarmored vehicle, motorcycle sidecar)
+	FT firepower
+ 3/2 *	Usable MG (not RMG) IFE + Passengers of CE armored HT + ½ * (Riders + non-BU Passengers not in armored HT)

FP halved if vehicle Eliminated or immobilized (inc. Shock/Stun, crew K/KIA/Break) in DFF before OVR
OVR FP halved vs Concealed target
Check for Random SW Destruction (A9.74) on an OVR KIA (-1 drm if fully-tracked)
If no Personnel are in the Location, SW/Guns in the Location are eliminated (A9.74)
Sanger and Gun inside are automatically eliminated if OVR by a fully-tracked Mobile AFV (F8.41) or if OVR result is a final KIA

OVR DRMs:

Armor Leader or Passenger Leader directing Passengers
TEM (NA if only FT firepower is used (D7.15), Crest TEM NA (B20.92))
Smoke
-1 DRM vs Inf/Cav in Open Ground (including Entrenchments, Emplacements, Shellhole, vehicle, Wreck, Bridge, Wall, Hedge, Bocage, Smoke)
+2 DRM for Motion vehicle targets and their Vulnerable PRC

Defensive Fire Options After OVR: (Reaction Fire)

Ordnance:

TH Case E and C-C4 as appropriate (C5.5)
Area Target Type NA (C3.33)

BFF From Bypass

Only turreted weapons pointing toward side TCA (D2.32)
Case A applies [EXC: Stabilized Gun firing at Acquired Target Or CMG/IFE firing at same target as last fired on (D2.321)]

BFF Footnotes:

r - TPBF (A7.21)	t - Mounted Fire [D6.1
s - Bounding Fire [D3.31D3.31	u - Motion Fire [D2.42

Vehicle may exit if able

Complete Trail Break (B13.421) as fully-tracked AFV exits Woods, Jungle, or Bamboo.
Vehicle must exit the Location before concluding another OVR

Staying in the Location:

Vehicle must be able to Shock/Elim an enemy AFV on an original TK/IFT DR of 5 in order to stay in that AFV's hex (D2.6)
Random SW Destruction for unpossessed or non-portable SW/Guns not in Pillbox/Entrenchment when OVR by a fully-tracked AFV if it ends the MPh in the Location (A9.74)
Concealed/HIP units are revealed if an "unbroken" vehicle (A12.1) ends the MPh in Bypass of their Location (A12.42)
All units are marked with a CC counter and are bound by TPBF Target Selection Limits (A7.212) [EXC: vs Unknown unit or unarmored vehicle with no Vulnerable PRC]
Surviving units are eligible to attack in the CCPh if able

Defensive Fire Footnotes

TPBF vs unarmored vehicle and Vulnerable PRC (including those BU in OT AFV).
PAATC (D7.21) required vs AFV if the unit is not exempt and has not yet taken a PAATC vs this vehicle in this phase. Failure of this PAATC Pins the unit and prohibits Reaction Fire [EXC: footnote m]. After performing a CC RF attack, mark the unit and all of its SW/Guns with First/Final Fire as appropriate; if the vehicle survives, mark the defending unit with CC to prohibit further non-CC RF attacks.
Including SW Ordnance and unpinned FT, MG, DC, MOL. (MOL NA for Infantry marked with First/Final Fire) (PF NA in SFF/FPF)
Vehicle target facing determined by the TH cdr: [1-2: rear 3-4: side 5-6: front] (D3.2). Underbelly Hits (D4.3) possible vs vehicle crossing Wall/Bocage/Dune Crest or exiting Depression (Gully/Stream/Wadi) via non-Depression hexside, or vs fully-tracked AFV OVRing a Sanger.
Non-CC RF uses the vehicle's rear target facing (Underbelly Hits NA). NA if unit marked with CC.
TH Case D also applies. ROF, FT, MG, MOL, and DC usage all NA.
CCV reduced by 1 because unit was marked with First/Final Fire. Ambush vs Bypass Vehicle NA.
Automatic Ambush vs Bypass vehicle (A11.8) unless Defender possesses a SW/Gun that is marked with First/Final Fire (D7.211)

Using TB Case E and (if applicable) TB Case A. The Gun's CA must change to include the hexside being crossed by the entering AFV, therefore the shot is NA if the Gun cannot do so (fixed CA due to previously firing from Woods/Bldg/Rubble, Pinned Crew, etc.)
Intensive Fire (TB Case F), one shot only, then mark with No Fire. NA for No-IF/No-Fire Guns.
Only for squads still able to First Fire a SW without using it as SFF/FPF. LATW marked with First Fire may not fire in SFF/FPF.
Resolved as FPF (A8.31)
Reaction Fire mandatory [EXC: vs unarmored vehicle with no PRC], even if Pinned (D7.212)
Must turn CA to match vehicle's VCA, but TH Cases A and E are NA (D7.212D7.22
OVR Prevention (C5.64)/ Non-CC Reaction Fire (D7.23). The Original TB DR acts as an NMC vs its manning Infantry. If the manning Infantry is Pinned or Broken as a result of this NMC, the TB attempt is voided (except for any malfunction result).
Unless marked with Final Fire or Intensive Fire and thus required to Reaction Fire per footnote m
Attacker may declare Gun Duel vs this type of defensive fire (C2.2401)
