SPA Battery*
*
The 2S1 (PsH74) SPA's in Finnish service are used to support the armoured brigades (with 2 Battalions forming an artillery regiment) and the newer mechanized battlegroups. The heavier 2S5s (Telak 91) are not brigade level assets but used by higher level command to bolster the artillery support of mainly attacking forces.*
*
The SPA battalion consists of 3 6 vehicle batteries. The battalion's fire is to be used concentrated for maximal effect rather than single batteries, yet single batteries can be used for example as mobile indirect fire support close behind the attacking forces to enable rapid use of artillery fire.*
