World War at Sea
By Steve Cabral
Add these rules to Second
World War at Sea section 20.0, seen
boats (MTB) are divided into five classes
with the following stats:
- MAS: 1 Hull, 1 Torpedo
- Vosper: 2 Hull, 1 Torpedo
- MGB: 2 Hull, 1 Tertiary, no Torpedoes
- Elco: 3 Hull, 1 Torpedo
- S: 4 Hull, 1 Torpedo
If scenario instructions indicate that a
player may use MTBs, he may deploy whichever
types are available to the navies he controls,
Britain: May use all five classes
of MTBs. 50% of all MTBs deployed must be
Vosper-class. Britain may deploy a maximum
of one S boat, but only from bases in Britain
United States: Uses Vosper and Elco.
Soviet Union: Uses MAS, and starting
in 1944 may use Lend-Lease Elco-class MTBs
at Murmansk only.
Germany: Uses S-boats. May also deploy
MAS, but cannot have more than 20 deployed
at the same time. Starting in 1943 they may
use Vosper (captured from Italy).
Italy: Uses MAS. Starting in 1942
they may also use Vosper, but at least 80%
of all MTBs they deploy must be MAS.
Japan: Uses only MAS.
Romania: May use up to 7 MAS.
MTB Night Attacks
Use the normal MTB Attack rules at night
(20.6), except that enemy ships can fire at
all MTBs that make nighttime surprise attacks
on them, AFTER the MTBs make their attack.
Halve the number of dice rolled by such enemy
ships (round fractions up).
MTB Daytime Deployment
Navies used MTBs during the day only in
certain desperate situations. A player who
wishes to deploy MTBs during daytime rolls
one die. A modified result of one or less
allows him to do so. Subtract one from the
roll in 1939-40 for all navies, and in 1941-42
for the U.S. Navy only.
MTB Daytime Combat
If MTBs contact an enemy task force during
the day, they fight the enemy task force on
the battle board in normal surface combat
The MTB-owning player may use spare multiple-ship
counters to represent the MTBs. The player
should write down which counter represents
which MTBs if there is more than one class
of MTBs in the flotilla.
Japanese MTBs are Speed 3; all others are
Speed 4. Russian MTBs (only) may move two
hexes per impulse.
Enemy ships may fire at MTBs on the battle
board with all their gunnery factors, but
they fire at half-strength (round fractions
up). Primaries may not hit MTBs at a range
closer than 5 hexes, and Secondaries may not
hit MTBs at a range closer than 3 hexes. Tertiaries
have no special range restrictions, and AA
factors may fire at MTBs at a range of 1 hex
