The RM-70 is a wheeled self-propelled, multiple rocket launcher that is used exclusively by Czech military forces in ArmA 2. It was added with the release of the Army of the Czech Republic DLC.

Overview

  • Role:

Design

Using an 8x8 truck chassis as its base, the RM-70 is a 122 mm multiple rocket launcher that was developed to replace the older RM-51 MRL in Czech service.

Armament
It is armed with a 122 mm rocket artillery pod on the rear flatbed, and has up to 40 high-explosive (HE) rockets stored, ready-to-fire. The cab-mounted UK-59 medium machine gun on the other hand, feeds from a single 100-round 7.62 mm belt box and has a further two more boxes to spare.

Features
Capability and role-wise, the in-game RM-70 is almost identical to its Russian-made counterpart in several ways; its launcher pod for instance, is loaded to fire the same munitions used by the BM-21 and also carries the exact same amount of rockets as the former.

The main difference with the RM-70 is that unlike the BM-21, its cab is armoured and uses reinforced glass that provides better protection for the crew from small arms fire. It is also unique for possessing a roof-mounted MMG, which allows the vehicle's crew to defend themselves from enemy infantry that get too close.

Mobility
The RM-70 controls better on unstable terrain compared to the BM-21, and handles more smoothly while driving off-road as well as being able to accelerate faster on all surfaces.

Drawbacks
Its only downside stems from its munitions, which have significantly less destructive power compared to the 227 mm rockets fired by its American counterpart; though as compensation it does carry more spare rockets (the M270 is limited to 12 rockets at maximum whereas the RM-70 has 40).

Crew Capacity
The RM-70 has a total of four seats in its cab; two main seats for the primary crew (the driver and main gunner) and two more for a secondary gunner who handles the roof-mounted UK-59, along with one spare seat for a passenger.

Capabilities

The RM-70 is capable of launching all 40 of its rockets in less than 32 seconds.

The overall range arcs of the RM-70 vary from:

  • Minimum: 1,450 to 3,330 metres
  • Moderate: ~3,129 to 5,000 metres
  • Maximum: ~4,002 to 10,100 metres

Because the artillery computer is actually incapable of firing at distances of less than 3,300 metres (this is the upper limit of the RM-70's minimum range arc), its true minimum range begins at 3,300 metres instead of 1,450 metres.

Its maximum range on the other hand, is shorter than that of the M270's, but makes up for it by being able to potentially land up to 20 rockets at the same location in a single volley by staggering its fire (the gunner must manually adjust the pod's azimuth to simulate MRSI).

Trivia

  • Unlike the other two rocket artillery vehicles, the RM-70 is not configured to be usable with the Artillery support module in the editor, which makes it completely unusable by the AI without modifying the settings of the module itself (at the config-level).
    • This bug continues to exist in the latest Steam versions of the DLC and has yet to be fixed by the official patches.
  • The RM-70 is the sole MRL vehicle of its kind in ArmA 2 that is armed with a cab-mounted MMG.
