INS Vikrant is an aircraft carrier.
INS Vikrant (IAC-I) is India’s first indigenously designed and built aircraft carrier. It was commissioned into the Indian Navy in September 2022, marking a significant milestone in India’s Atmanirbhar Bharat (self-reliant India) initiative and enhancing the Navy’s blue-water capabilities.
INS Vikrant is the largest warship ever built in India. It is named after its predecessor, India’s first aircraft carrier, which was acquired from the UK and served from 1961 to 1997. INS Vikrant operates a mix of aircraft, including MiG-29K fighter jets, MH-60R helicopters, and other naval aviation assets.

The correct answer is Jodhpur, Rajasthan (A).
The Indian Army is raising its own fleet of AH-64E Apache attack helicopters. The first squadron for the Army Aviation Corps was established at Jodhpur, Rajasthan. This location is strategically important for operations, particularly towards the western borders.
The Indian Air Force already operates Apache helicopters, but the Army acquiring its own fleet marks a significant enhancement of its combat capabilities, providing dedicated aerial fire support and reconnaissance assets directly under Army command. Jodhpur serves as a key airbase in the western sector.

The correct option is D) Smoke bomb. Smoke bombs are generally used for creating smoke screens for concealment, signaling, or crowd control, and are not standard equipment used by Bomb Detection and Disposal Squads for the process of detecting, identifying, accessing, rendering safe, recovering, and disposing of explosive devices.
BDDS equipment typically includes specialized tools for remote handling (like telescopic manipulators), protective gear (like bomb blankets and bomb suits), detection devices (like deep search metal detectors, explosive trace detectors, X-ray machines), and tools for rendering devices safe (like disrupters).
Other common BDDS equipment includes remote-controlled vehicles (robots), specialized tools for gaining access (like entry tools), and various types of disrupters (like water cannon disrupters). The focus is on minimizing risk to personnel and safely neutralizing or disposing of explosive threats.

CISF dog squads are primarily trained for security purposes, which include detection of explosives and narcotics. IEDs (Improvised Explosive Devices) fall under the category of explosives. Narcotics detection is also a standard function. While dogs *can* be trained for metallic weapons, it is less common than explosives or narcotics detection in general security contexts. Detection of specific food items like pickle or general smuggled food items is not a typical task for security force dog squads. Therefore, sniffing and identifying Narcotics (2) and IEDs (4) are standard capabilities.
Security dog squads are commonly trained for explosive detection (including IEDs) and narcotics detection.
Specialized dog squads are vital assets in security operations, particularly at airports, industrial units, and sensitive locations guarded by CISF. Their olfactory capabilities are leveraged to detect substances or items that pose security threats, with explosives and narcotics being primary targets due to their association with terrorism, smuggling, and crime.

All four factors listed – Terrain, Command and control, Direction of fire, and Maximum firepower within minimum time – are main considerations that affect how a military platoon or section is formed and deployed in tactical situations.
Effective tactical formations are designed to leverage the terrain, ensure clear command and control, allow for concentration and direction of fire towards the enemy, and maximize the unit’s ability to deliver firepower quickly and effectively.
Military tactics emphasize adapting formations based on the specific environment and mission. Terrain influences movement, cover, and fields of fire. Command and control require formations that facilitate communication and supervision. The threat direction dictates the orientation of the formation to bring weapons to bear. The overall goal is to achieve superiority, which involves optimizing firepower delivery.

A standard fire control order (often remembered by mnemonics like GRIT or similar) in fieldcraft and tactics includes specifying:
1. Group: Who is to fire (e.g., “Section”, “No. 1 and 2”).
2. Range: The distance to the target.
3. Indication of target: Clearly identifying the target (e.g., “Enemy machine gun on hill”, “Two figures by the tree”).
4. Type of fire: How to fire (e.g., “Rapid fire”, “Deliberate fire”, “One burst”).
All four elements are essential components of a complete fire control order used to effectively direct troops’ fire onto a target.
A comprehensive fire control order includes specifying the firing group, range, target identification, and type of fire.
Issuing clear and concise fire control orders is a fundamental skill for leaders in the field to ensure effective engagement of targets and control of firepower.

In fieldcraft and tactics, natural cover provides protection from enemy fire, while natural concealment hides you from observation. Ravines, hollows, and reverse slopes are terrain features that can offer significant protection from direct fire, thus serving as natural cover. A bush primarily offers concealment (hiding from view) but provides very little, if any, protection from bullets. Therefore, a bush is the option that is *least* likely to be considered natural *cover* compared to the others, which are primarily terrain features offering protection. While a bush is a natural feature, its role is more about concealment than cover.
Cover protects from fire; concealment hides from observation. Ravines, hollows, and reverse slopes offer significant cover. Bushes primarily offer concealment with minimal cover.
Effective fieldcraft involves using terrain and vegetation to gain an advantage, combining elements that offer both cover and concealment whenever possible. However, the distinction between the two is crucial.
