3. Bamboo

3.1 Whenever PTO Terrain (G.1) is in effect, all brush becomes bamboo. Bamboo is treated as dense jungle except as stated otherwise.

3.11 BROKEN UNITS: A broken unit may claim a -1 Rally DRM in bamboo only if in a pillbox. A broken unit is not required to rout to the nearest bamboo hex.

3.2 ENTRY: Infantry may enter bamboo only via Minimum Move (A4.134), Low Crawl (A10.52) or Advance vs Difficult Terrain (A4.72) [EXC: they may use a path/TB, but if they do they may not then exit that bamboo hex via a non-path/non-TB hexside during that same phase]. Infantry may "lead" horses into/out-of bamboo only along a path/TB, and Cavalry may enter/exit bamboo only along a path. Manhandling into bamboo is NA except along a TB. For Defensive First Fire purposes, the number of MF considered expended during a Minimum Move into bamboo equals the unit's printed (or Inherent) MF allotment plus one (or plus two, at night).

3.21 STRAYING: Straying can occur in an Interior bamboo hex (i.e., a brush hex adjacent to six other woods/brush/marsh hexes) as per 2.22.

3.22 SEARCHING: Searching an Accessible bamboo hex counts as Searching two hexes. Q&A

EX: If a unit's Final Search dr is ≥ 5 it cannot Search an Accessible bamboo hex. If that dr is a "4" the unit can Search one Accessible bamboo hex or two Accessible non-bamboo hexes. If that dr is a "3" the unit can Search one Accessible bamboo hex and one Accessible non bamboo hex, or three Accessible non-bamboo hexes.

3.3 LOS/TEM: Bamboo is a one-level obstacle and normally has a + 1 TEM. However, its TEM is -1 for any DC, Bombardment or ordnance/OBA HE attack [EXC: not for any type of HE Equivalency or Specific Collateral Attack, nor vs a Partially Armored AFV] vs an unarmored target in it. The Residual FP of an attack that received the bamboo -1 TEM is increased by one IFT column (like Air Bursts; A8.26).

EX: A 75mm Gun using the Area Target Type to fire at Infantry in bamboo attacks with six FP and a -1 DRM (bamboo TEM) on the IFT, and a hit can leave four Residual FP instead of two. If it instead uses the Infantry Target Type it applies the bamboo -1 TEM as TH case Q, and a hit can leave eight Residual FP instead of six.

3.4 GUN: A Gun set up in bamboo is never considered Emplaced, but may still use HIP as per A12.134 unless otherwise prohibited. A non-vehicular Gun in bamboo has its firing and CA-change capabilities restricted as per B9.531. See also 3.2. Q&A

3.5 FORTIFICATIONS: Neither wire nor entrenchments may be placed in bamboo, but pillboxes/mines or Panjis (9.) may. See also G.2 for HIP.

3.6 FIRE: The Kindling and Spread numbers for bamboo are "10". However, the applicable EC DRM is doubled when checking for Kindling in, and for Fire Spreading to/within, bamboo.¹⁴

EX: Infantry attempting to Kindle bamboo during Wet EC must add a -4 EC DRM to their Kindling DR (-2 [Wet EC DRM] x 2 [bamboo] = -4). A Flame-to-Blaze DR (B25.151) made for a Flame in bamboo during Dry EC would receive a +2 EC DRM.

3.7 PARACHUTES: All parachutes landing in bamboo are treated as if landing in woods; i.e., E9.42 applies in the normal manner.

3.8 MISCELLANEOUS: Special rules for FG, Detection, Recovery, Ambush and trip flares apply in bamboo; see G.3, G.4, G.5, G.6 and G.8 respectively.
