If a friendly Grand Offensive is carried out using Tanks (anywhere), no test
of Tank values takes place elsewhere.
In all instances, there may only be one Tank value test per turn (for one
side).
Tank values may only increase from the test. Once a level is achieved, the
tank may not drop below this level.
Tanks: Entente and Central Powers
Each side has its own Tank value, evolving during the offensives.
Nonetheless a limit exists: the gap between the adversary’s value may be
no greater than 2. As a consequence, the side with the lowest value will
always have its tanks increased by this method.
21.13.2 Tanks in Combat
Tanks as Support
A Tank adds its support value to an “engaged” friendly unit. But it is fragile
and risks being destroyed during combat. Thus, it is better to have several
Tanks present in order to benefit from support for several rounds.
A Tank may support any corps at all, with the condition that a national corps
is in the stack at the beginning of the battle (whether he is engaged or not).
This tank support is additional to artillery support. A Tank doesn’t spend
any MUN to be used.
Reminder: a Tank is always worth 1 in defense unless alone.
Tanks and Trenches
Tanks may benefit from the Infiltration Tactic. Infiltration has the goal of
diminishing enemy trenches at the beginning of the battle.
To use Infiltration, it is necessary to carry out a major battle (4+ corps) and
to have at least 2 Tanks to engage in the 1st round (one per sub-battle).
Then, the player may commit additional tanks as he wishes.
Each time the “Main” battle of a Grand Offensive is won (Target region
taken), the Infiltration Tactic becomes more and more effective with Tanks:
permanent bonus of +1 to reduce the trenches (max. +2).
If there is only 1 Tank, the Infiltration Tactic may not be used, but the Tank
keeps its normal bonus (support in combat).
Tanks and Battle
A Tank, once engaged in combat, must stay there the whole battle. It may
not be disengaged until the battle is complete or the tanks is destroyed.
On the other hand, nothing obliges the player to engage a new Tank if one
Tank is destroyed during a round (except to respect the minimum of Tanks
engaged). But, if he does, this new Tank must stay engaged.
A HQ may send Tanks from his reserve to reinforce during a battle, as well
as one corps. The same for the GHQ.
Tanks and Losses Sustained
If the unit engaged in combat has sustains a loss (even at which inflicts no
damage), the supporting Tank may be destroyed. This is checked on the
Tank Destruction Table:
Light Tanks
Tanks may be placed in the HQ or GHQ Reserve. A light Tank does not
count in the reserve capacity. Light Tanks in reserve may be used during a
flank or in depth breakthrough.
Heavy Tanks
Heavy tanks may be placed in a HQ’s reserve, but they may not participate
in an in depth breakthrough. Heavy tanks in reserve may only be used in a
flank breakthrough (never in depth).
The GHQ may also have heavy Tanks in its reserve.
21.13.3 Production of Tanks (in short)
Germany, Austria, England, France and the United States may produce
Tanks. Russia may build them too, but at the earliest 2 years after the other
powers have produced their first tank unit. Requirements and constraints
are:
● It is necessary to possess the “Heavy Tank” technology.
● In the beginning, the production rate is limited to 1 Tank per
Interphase.
● A Tank is built in 4 turns.
● Tanks are support units. It is necessary to stagger their production
over several turns (i.e. mixed with the other support units).
See 21.6.2 for more details.
