MCQs 60 Flashcards
——- is one of the oldest and simplest form of cannon
Mortar
Its ——- enables the projectiles to clear high ground and mountain tops
High angle of fire
There is a need for such a weapon where ——— fail to destroy the enemy, so mortars are the only weapons which are effective in such areas
Flat trajectory weapons
To obtain effective fire on the targets and to get the best use out of this weapon, it is essential that, the commanders understand its ———, —— and ——— thoroughly
Characteristics, capabilities and limitations
The elevation of the barrel varies between ——- at maximum range and ———- at minimum.
45 degrees, 80 degrees
The high angle of elevation enables its bombs to achieve a high angle of ——— and ———
Ascent and descent
The vertex height of of its trajectory varies between —— and —- at charge 0, —— and —— at charge 1, —— and —— at charge 2
225 meters, 115 meters, 364 meters, 186 meters, 785 meters, 421 meters
It can be sited and brought into action from behind high cover, where it will be safe from the ———-
Enemy’s small arms fire
It can engage targets on reverse slopes, dead ground, ——— etcetera, where the —— are ineffective

Due to ——— and flash produced while firing. It can be easily detected by the enemy if it is not sited behind ——- or in low ground
Distinct sound, cover
Moreover mortars can easily be located by ——- and ——— equipment, even if sited behind cover, so these are always liable to counter me

Effective fire can be brought down on targets which have been ——, during night, fog or ———. The mortars can also engage ——- at night
Pre registered, smoke, new targets
It is very accurate weapon thus it does not have much of ———. The weapon can even destroy ——- targets effectively
Dispersion zone, point targets
If the ———- is not coordinated with the barrel and apart from many other factors like wind, ammunition and ——— to the target, the first bomb may not fall on the target, therefore we can adjust the ———, so that the subsequent bombs land on the target through the process of range
Mortar sight, wrong estimation of range, elevation
As the time of flight of the bomb varies between ———— for different ranges and charges
10 and 25 seconds
The wind will have an appreciable effect on the path of the bomb, where the time of flight is more than ———
15 seconds
